How to rob an SSD disk. How are magnetic disks shaped like hard disks. Reduced the number of rewrite cycles

Golovna / Korisne PZ

Until recently, for the preservation of data, there were victories carried out, which are based on the principle of magnetic recording. In the 70s and 80s of the last century, they were floppy diskettes, and then more superficial and misty hard disks were sacrificed. Such a camp was right to wait until the end of the last ten years, until SSDs appeared on the market - solid-state electronic wear, mitigated mechanical parts and breathed high swidkod.

A bunch of stench was stunned by a small amount and a high price. The term of the service tsikh deviceіv tezh bazhav krashgogo. That's why, for food, now the need for SSD accumulating, there was no obvious change. With an obligation of 32 or 64 GB and the price of a kilka, hundreds of dollars and a nose were given as an expensive toy. And the lack of speed in writing / reading speed (up to 1.5-2 times) was not significant;

Ale, progress does not stand on the spot, and in no time at sales there were some and available solid-state accumulators, which won the respect of a wide audience. Food, most needed hard drive SSD becoming relevant, like no way.

Design features, advantages of SSD disks

In order to understand, now put a storage SSD, it is necessary to study the main advantages of such disks. Do not make the nobility golovnі nedolіki tsikh gadgetіv.

Construction of HDD and SSD disks

The most common type of SSD in traditional hard drivesє іnshiy principle I will arrange that work. At the top of the HDD, the design of solid-state noses has no mechanical components. To record data victorious arrays of high-capacity flash memory, access to which secure internal controller. This design gives the SSD a number of advantages that are inaccessible to the classic HDD.

Silence. Zavdjaki vіdsutnostі rukhomih elementіv v protsesі Robotic SSD do not see sounds.
Stіykіst to struіv. On the front of the HDD, in the process of moving I will add or a falling magnetic head can scratch the surface of the disk (thereby damaging її and data, which are saved), SSD is less irritating. Obviously, after a blow to the case, the contact between components can be damaged, or accumulated, damage to the middle of the computer or laptop, theft from the whole world.
Male energy recovery. The main energy saver in the railway is the motor that drives the disks. Wines are wrapped up with a turnover of 5, 7 or 10 thousand turnovers for a piece of fluff and stained glass up to 95% of the cost of electricity supplied to the accumulator. In this way, SSDs are up to 10 times more economical, which is especially relevant for thin laptops.
High speed of reading/writing. Magnetic method for recording data of reach between perfection. More than 100-200 Mb / s in the post-record mode, without reduction in the term of service, increase in dimensions, increase in power supply and increase in price. hard drive impossible. Flash memory SSD is not minus and works up to 10 times faster.
Stable swidth of robots. Likewise, information on a traditional hard drive is recorded on physically different disks (their HDD designs are 2 and larger), or else there is a stutter, and the need to move the head, which is read. The speed of the work is significantly reduced through the tse. A similar stutter when reading the middle array of SSD flash memory becomes millions of fractions of a second and does not directly affect overall productivity.

SSD shortfalls

For all the advantages, it's too early to talk about the thoroughness of SSD technology. The lack of such storage capacity is insufficiently low cost (3-10 times more expensive for an HDD for a 1 GB memory storage space) and a smaller resource of work (from 10 thousand to 1 million cycles of overwriting on a computer). This indicator of the HDD is theoretically unobstructed, but in practice it reaches dozens of millions of cycles.

Another minus of solid-state accumulators is electrical volatility: when applying high voltage caused by a malfunction of the life block, the controller lights up, and the flash memory burns.

SSD accumulators - now you need stink

Knowing the main advantages of solid-state storage devices, power supply: “Is an SSD disk needed for a computer?”. much simpler. Purchasing this gadget will allow us to improve the comfort of the gadget and last an hour of autonomous work (like a portable PC). The high speed of the robot and positively sign up for the hour of the OS occupancy, the review of documents and productivity in games.

New SSD disk is required for a laptop

If there is a laptop on the right, then here the power supply “now you need an SSD” can not be put up for discussion. At any time, I won’t be worse than buying a solid-state wear. Energy-efficient technology allows reaching more hours of work in one charge, the presence of life-giving lances in high voltage minimizes the risk of a non-reversible drive out of tune in the event of a power supply failure, and the memory in a portable PC is not important,

What is the cost of a smaller resource of work, dosvid service centers show: hard drive of the laptop to get out of tune and subject to an hourly charge in a few times and more often, lower at a stationary computer. It's tied up, we're ahead, it's significant great kіlkistyu dynamic navantazhen, how the device is supposed to be transported and operated. Vipadkovo having missed the laptop from the knee at the moment, if you are recording data on the HDD, the great risk is to get the accumulator out of tune, to start it visually without damaging the computer. To that high ymovіrnіst, scho SSD to serve navit more, nіzh zalіznichny.

New SSD drive for a gaming PC

Gamers - head, at the same time, part of the buyers of SSD. Stopping a solid-state accumulator allows it to reach the shortest productivity in trivity games for the speedy hour of the next launch. Expectation of equals, inventory, other objects and other elements of the game world from files that are saved on the disk are also marked significantly (up to 10 times) more.

There is a difference in "seamless" games, such as Skyrim, grand theft Auto or Fallout. Their inner light is spread out on one great map, and for changing the attraction to the outside, one part is saved in the operational memory. You can also have a situation, for example, within a radius of 200 meters around the character. At the world, passing through the space, objects that are removed from the RAM are seen, and objects are recorded on their space, near which graves are approaching. In this way, reading from a hard disk is easy and unimportant to guess what to give data to the SSD processor to allow more efficient and lower speed.

For gamers, the high capacity of a gigabyte in a solid-state storage device is not critical; For example, a collection of 100 films like FullHD is about 1 TB, the same Fallout 4 needs less than 50 GB of free space.

Newly needed hard drive SSD for multimedia computer

For a home PC, which is the best choice for web surfing, that kind of multimedia tasks (watching movies, listening to music) SSD storage is the least necessary. I need such a disc to be more connoisseurs of content like Blue-Ray. Check, download a movie, 40 GB in size, sign up for a riddle about a PC, finish it for a long time (approximately 10 minutes). Ale for picking up your favorite movies in FullHD, QHD or 4K UHD you need 500, 1000 or 2000 GB SSD spaces. The number of such hoarders exceeds a thousand dollars, and if you allow yourself such a dressing, it can be far from leather.

For incompetent short PCs, a great SSD for a multimedia computer without much need. Possibility of classic (magnetic) hard disks is enough to satisfy the needs of 99% of cores. Tim is not smaller, a small (64 - 128 GB) solid-state accumulator, which wins as a system wearer (for Windows installation), we will not call. Vіn allow to significantly increase the sound code of the PC, reduce the noise level. system unit and save electricity.

A great chanel of Chinese technology, an amateur of clear screens. An adjunct of healthy competition between vineyards. It's fun to follow the news from the world of smartphones, processors, video cards and other halls.

Solid State Drives (SSD) are new and hard drives that are a good alternative for hard drives HDD, what else do you need? Read on, how we demistified a solid-state accumulator. The rest of the year is a poster to commemorate the obligation to release SSDs and lower prices (though it is obviously not possible in this way to reduce the prices between SSDs and traditional hard disks).

What is an SSD? How do you play with an SSD drive? What do you need to work differently from an SSD? Read on to find out everything about solid-state accumulators.

What is a solid-state accumulator?

You can but it is important to believe, but hard-boiled accumulating materials can be done with old technology. Solid-state accumulators lasted for decades in various forms, the most expensive ones based on operational memory, and were only installed in ultra-high class and super computers. In the 1990s, the first SSD was built on the basis of flash storage, but the stinks were too expensive for the slow market and were marked by ice beyond the boundaries of specialized computer clusters. During the 2000s, prices for flash memory continued to fall, and until the end of the decade, solid-state storage devices appeared on the personal computer market.

Father, what is a solid-state accumulator? Here it is necessary to see at a glance those who are a traditional hard disk (HDD). A hard disk is a set of metal plates coated with ferromagnetic material that are wrapped around the spindles. Recording on the surface of magnetic plates is made with a critical mechanical handle (important drive) with a thin sting (head). Data is saved for changing the polarity of magnetic battles on the surface of the plates. Well, obviously, it’s a little more foldable, but to say that everything here is broken by the analogy of an automatic handkerchief programmer, his hand shuffles the track on the record, so the drive handle and the heads of the hard disk whisper data. If you want to record or read data from magnetic hard disks, the plates are wrapped around, your hand is searching and knowing the data. This is the very mechanical process, shards of digital wines.

Solid cumulative, navpaki, do not wash the parts that are crumbling. Although the scale is different, and the area for saving on the HDD is significantly larger, and the solid-state storage device is larger than the sleeping one with a simple portable flash storage device, lower with a mechanical hard disk (i, obviously, more richly, if you don’t, with a tape recorder) Overwhelmed! most solid-state storage devices on the market - all NAND flash memory, a type of non-volatile memory, which does not require electricity to save data turn on). NAND memory is also safer for better security, more low mechanical hard disks, so it’s an hour, stained glass if the plates are spinning and don’t shuffle, the data is seen from the level.

Pairing of solid-state accumulators from traditional hard disks

Be sure to know that such solid-state accumulating, but even more beautifully equalize them with traditional hard disks, which vibrate even richer rock. Let's take a look at the sprat of key features in the streaming line.

Spin-hour: SSD-accumulators do not waste "spin" hour; kopichuvach not maє parts that collapse. Zhorstkі disks mayut different spinovy hour (sound a few seconds); If you feel a whirrrrrr clatter on the whiling or two when the computer is accessed, or when accessing the files, which rarely chirp, you will definitely feel the wrapping of the hard disk.

Hour of access and zatrimki to data: hard-to-accumulate data is hard to know data, as a rule, it is an order of magnitude higher for 80-100 times, lower hard disks; passing mechanical plates, which are spinning, and if it is given, then the stench can take away access to data mayzhe mittevo. Shvidkoy search for data on hard disks change the physical movement of the anchor and the wrapping of the plates.

Noise: SSD storage noise; the presence of roiling elements means the presence of noise. Zhorstkі discs vary to achieve quiet, even strong equal to the sound.

Sustainability: okremі brіbnіchі і power aside (bad disks, firmware, power is thin) SSD-disks went ahead of the plan of physical reliability. More important is the failure of the hard disk due to mechanical failures; As a matter of fact, after ten thousand years of work, the mechanical drive just wears out. Sens has a cycle of reading/writing hard discs.

From the other side, solid-state accumulating materials may be surrounded by a large number of cycles of recording. Tsya is surrounded by a large number of cycles of recording є head power for scheduling solid-state storage devices, but the reality is that an average short-term computer is unlikely to be able to work a lot of cycles of reading and writing to an SSD. Intel X25-M, for example, can process 20 GB of data for 5 years without a hitch. How often do you erase and write 20GB of data on the main drive on a free basis?

In addition, SSD drives can be recycled; if the NAND modules have reached the end of their write cycles, the stink becomes less readable. The disk will then read data from a small sector and rewrite it to a new part of the disk. Crim bliskavki or a catastrophic short-lived design, the drive SSD is more similar to "old age, why is it in my brushes!", and not to the phrase "boom!" HDD bearings!” that yoga bitch. You will have enough time for backup your data and pridbati new disk.

Effort: SSDs run 30-60% less power than traditional hard drives. Savings in 6 or 10 watts of money are not rich, but with a stretch of fate or two on a heavily used machine, everything converges.

Varity: SSD is not cheap. Traditional prices for a hard drive have fallen by about five cents per gigabyte of data. Hard-drinking hoarders are richly cheap, lower stinks were 10-20 years old (if the stinks were surrounded by special computer systems), Ale stink still dosit dear. Depending on the size of that model, you can check to pay here between $1.25-$2.00 per GB.

Keep an eye on solid-state SSD accumulating

In management operating system, saving data, and interoperability with your computer kіntsevy koristuvach, under the hour of work of the SSD disk, є increase in speed. If you reach the turbo from the right about the disk, then there are rules that may have a greater meaning.

Do not defragment the drive. Defragmentation Marne for SSD and change the trivality of your life. Defragmentation is a technique to know the details of the files and optimize them on hard disk platters in order to change the time spent on the disk. SSD do not wash the platters, but it may take a little more time for a joke. New defragmentation causes more write cycles. Locked in Windows 7, defragmentation was disabled for SSDs.

Turn on indexing services: as your OS can be a little trick - an addition tool is such as indexing service, turn it off. The hour of reading on the SSD is fast, which you really don’t need to create an index for the file and the process of indexing the disk itself and writing the index will be more appropriate on the SSD.

Your OS can support clippings. The TRIM command allows your OS to communicate with the SSD and warn you that blocks are no longer broken. With the help of the team, productivity on SSD is very degrading. This publication for Windows 7, Mac OS x 10.6.6+ and Linux with kernel 2.6.33+ supports the TRIM command. A haki register supplementary programs Use to change more early versions of the OS, such as Windows XP, to type the TRIM command. Your SSD drive is paired with a modern OS for maximum productivity.

Leave a part of the disk empty. Reversing the specifications for the outbuilding, most of the pickers recommend trimming 10-20% empty. This empty space helps the virtualization algorithm (they transfer data through the memory of the NAND modules, to minimize the total loss on the disk and ensure the trivality of the term of service and the optimal characteristics of the drive). If you deprive yourself of a little space, then the algorithms of vir_vnyuvannya will lead to an hourly wear on the disk.

Media to another drive: SSD storage is expensive, so there is no point in saving your massive media files to your expensive SSD storage. You can choose traditional hard discs 1 TB and beat the big one appendage disk(however possible) to save great and static files (for example, movies, music collections and other multimedia files).

Invest in a riddle: compared with hard-core storage devices, RAM is cheaper. The more RAM you have installed, the less cyclic writes to disk. You can prolong the life of your expensive SSD drive by ensuring that your system has the correct operational memory.

A solid hoarder for me?

At the moment, you have a lesson in history, a stream of threading, and a day to help your SSD in a wonderful form, but do you need an SSD drive for you? Designate all relevant options and get ready for the offensive:

May take a hit hour: You can switch to cold take to browse web pages in less than a second from an SSD; at the same time, you could often spend more money for a drink with a traditional hard disc.
Do you want swedish access for foreign programs that igor: we have already said a lot of times, but hard-boiled accumulating and superimposed ones.
You want a more quiet and less agile computer: as if it were louder, SSD-accumulators will run and save significantly less energy.
You can rip two discs: one for OS and one for files: you can save less family photos and CD-Rip or two, you will need more available traditional HDD to save great files.
You are ready to pay a significant amount for an SSD-storage device: the highest price for this day is a sum per gigabyte, and also an hourly increase in productivity of 3000%.
If your list looks up, down, empty, and if you want to take care of the speed of work, then SSD is for you!

Today on the market of computer storage hard drives are represented by two main types - SDD and HDD. Which of them is the shortest? Let's take a look at which food in detail.

HDD - classic hard drive

HDD- this is a classic hard disk, which is a box, where round magnetic plates and heads are placed, which are read. Data is stored on the magnetic plates, and the heads, which are read, obviously, data are read. Principle robotic HDD resembling a gramophone, but the speed of the spindle wrap is richer. HDD spindle spinning magnetized plates with 5400 and 7200 wraps per fluff. The price of the widest width of the HDD spindle wrapping, used for computers. Spindle wrapping speed can be even more rich - for example, 10,000 or more wrappings per piece, but still the same as the standard of the server side.

HDD useredin / forumrostov.ru

What is the speed of the HDD spindle wrap? This pokanik often wins the speed of reading and recording with a hard disk of data - the greater the speed of the spindle wrap, the greater the speed of reading and recording of data. But we don’t call it like that, shards on HDD shvidkodіyu vplyvayut іnshі yogo pokazniki – tse shіlnіst і recording і hour of sufficient access.

The greater the indicator of the recording capacity, the faster the HDD will be. Entry strength current HDD- 100-150 Gb/sq.in. With a show of sufficient access, all at once, even for an hour, for some kind of hard disk, we performed the operation of reading or writing data on a magnetic plate. Father, what is less than an hour, then more beautifully. The range of this parameter should be set from 2.5 to 16 ms.

In this rank, a robotic computer has a difference between two HDDs and a spindle speed of 5400 and 7200 can be unremarkable.

HDDs are also subject to physical dimensions and technical characteristics models are indicated only up to their width. Ce size 3.5 inches standard size HDD for folding PC - 2.5 inches - size HDD for laptops.

SSD - a hard drive of a new format

SSD- In the technical characteristics of computer attachments, you can also use the name "solid-state storage device" - in fact, the volume of the flash drive is the largest, in the same HDD, it is easy to read and write data. SSD faster HDD at 3-4 times. For real Windows takeover, installed on the SSD, it takes no more than 10 seconds, at that hour, if the operating system on the HDD will start to take a break.

What is the secret of SSD code? HDD, for example, with Windows startup spend an hour looking for sectors on a magnetic plate and moving heads that are read. At startup, such Windows versions With the same functionality on the autoload SSD, it simply reads the data from a specific matrix block, where the data is to be found. On the SSD-storage, a smarter and operating system, programs, and other files are launched.

SSD in the middle

SSD does not give a special load to laptops, even if the stink is no more than 100 g.

On the vіdminu vіd HDD, SSD don't be afraid to hit that fall. And the axis, having inadvertently missed a laptop, you can add to your own trouble - and on replace HDD, and revival of data.

SSD works silently, at that hour, as a garniy swidkіsny HDD, you can wake up to sleep, if the computer is left out of the night.

Before speech, about the renewal of data for which power SSD program the HDD. Retrieving data from an SSD is problematic. As, for example, there will be a voltage drop in the electric circuit, the SSD will burn out in full and all data will be low. And the axis of the HDD in such a way to burn is less than a small fee, with which all the data is left on the magnetic plates. For bajannya IT-fahivtsі tsі danі can vodnoviti. Those same worthy and renewed earlier in the distance coristuvachem tribute for special assistance software. For more SSD-accumulators innovations files away after the cleansing of the cat, do not go into it. And above these power sources, the SSDs are already working, moreover, the existing models of solid-state accumulators can not physically clear the matrix blocks from the data records at the time of the arrival of the coristuvach command, but work harder if you need it.

Alece is far from being the most diverse place of solid-state accumulators. Їхні nedolіki so suttєві, like і perevagi over HDD.

First, the price. SSD cost more expensive. For the price of a 60 GB SSD storage, you can buy a good HDD with 1 TB of disk space.

In a different way, the cost of a small amount - SSD with a total of 512 MB in the market of computer storage can be done rarely, where larger standards have a volume of 128 GB or 60 GB. Like Bachimo, so don’t roam the SSD with a complete add-on for the needs of a coristuvach, and just like that, I don’t go about a super-thin ultrabook, for a collection of files, all one laptop or a PC will have to complete the HDD. The choice to save data is less than SSD, we repeat, it can cost a decent amount of pennies.

Thirdly, the SSD may be able to clearly install the resource to recover. You can overwrite data on a solid-state storage device up to 10,000 times. There are no such HDDs, and it is rare if the hard drives change the hard drive for the same reasons. As a rule, tse mechanical failure, or overheating, or modernization. Vrakhovuchi high variability of SSD, computer attachments can be equipped with at least 8 GB of operational memory, so you can turn on the Windows download file. Even more overwriting of data in this file will help the SSD resource to get better.

SSD chi HDD: which is better to choose?

What is better than HDD or SSD? For the presence of large sums, obviously, the SSD in the warehouse of the PC or in the laptop cannot be brought. Irrespective of all technical imperfections of a solid-state accumulator, it is viable for victorious yoga as a system extension for Windows. As long as you don't get too shy to earn a lot of money, a good free HDD is a much more practical option.

Head photo: HDD in series with SSD / 123rf.com

Demi sorted out what it is, how it works, etc. But we didn’t say about those that hard disks actually lived out their growth potential, both in terms of efficiency and productivity, but they were replaced by modern solid-state storage devices or SSDs. Regardless of those that HDDs need to be made wider, SSDs have also become more popular, and gradually bring the outdated technology to the market.

Oskіlki the topic is popular and relevant, in the current article we will analyze it from SSD: we know what it is, what are the features of their work, show-offs, zagal - like a zavzhdi. Let's do it.

What is an SSD

SSD drive - computer is not a mechanical attachment, which is made up of memory microcircuits and a microcontroller. Look like the English Solid State Drive, which in literal translation means a solid state drive.

For whom the whole word is meant to be sensible. Non-mechanical attachment means that in the new there are no mechanical parts - the middle does not collapse, do not jiggle and do not make noise. Like a legacy - nothing is worn out, nothing is worn out. The shards of SSD drives came to replace the traditional mechanical ones, so power is more important. The old disks had terrible vibrations under the hour of work, solid-state storage devices- Ni.

The memory chips are chipped to save information. The controller on the disk allows you to take data from the middle memory and write it to them, transferring data to the main computer interface regardless of the specifics of the work memory. A giant flash drive is like an SSD drive, it can be seen at first glance, but only with a bunch of branded components.

Why do you need an SSD

Whether your computer has an SSD, I'll replace it with a better HDD. Vіn pratsyuє shvidshe, maє small dimensions and do not see sounds. The high speed of the program and operating system increases the comfort of the robot from the PC.

What is an SSD in a laptop, de leather wat energy for a rahunka? It was sensible, we were forward - it’s more economical than carrying information. Vіn building pratsyuvati іz battery charge more. Until then, the new arc has little space, which allows you to turn on the SSD in a compact hardware configuration.

Why an SSD is built

Small body, yakomu has a small paid fee– The entire SSD drive is called. On the board soldered kіlka memory microcircuits and controller. On one side of the box there is a special rose - SATA, which allows you to connect an SSD drive as if it were another storage device.

The memory chips are chipped to save information. These are not the ones that are in the skin computer. The memory of an SSD drive is to save information and then remember. Memory SSD drives energy independent. Just as data is stored on magnetic platters on a stellar disk, data is stored in special microcircuits. Recording and reading data is significantly faster, lower hours of work with plates of mechanical disks.

The controller on the disk is such a specialization of higher education, which can even effectively distribute data in microcircuits. Also, in part of the service operations, cleaning the disk memory and redistributing the middle ones when they are worn out. For robots from memory, it is even more important to check service operations at the same time, in order to avoid wasting information.

Buffer memory, like the best disks, is beaten to cache data. Tse shvidka operational memory on SSD-storage. Data from the beginning are read into the buffer memory, changed into it, and then only written to disk.

How to process an SSD drive

The principle of operation of the SSD drive is based on the specifics of the memory core. The most widely used memory is NAND type. Data processing is done in blocks, not in bytes. In the middle of memory, the resource is cycled overwritten, so that more often data is written to disk, then more often it will be out of whack.

The reading of these data is very easy to read. The controller assigns the address to the block, which is necessary to rahuvati, and is sent to the required middle of the memory. Even though a few non-sequential blocks are read in the SDD, the price does not show up on productivity. Just go to the next block at the next address.

The process of recording data is complex and consists of low operations:

reading a block into the cache;
change of data in cash memory;
implementation of the procedure for erasing a block on independent memory;
writing to a block in flash memory for an address calculated by a special algorithm.

Recording the block takes a few years until the end of the memory on the SSD disk. There is an additional operation to clear the block before writing. So that the middle parts of the flash memory were worn out evenly, the controller calculated the numbers of the blocks before recording with a special algorithm.

The Block Erase (TRIM) operation is performed by SSD drives for an hour of downtime. Tse to fight in order to speed up the hour of writing the block to disk. When writing, the algorithm is optimized by the way of the erasing step: the block is simply indicated as valid.

The operating systems can independently beat the TRIM command to clean up such blocks.

See SSD disks

Usі SSD disks pod_lyayutsya k_lka vid_v stale v_d tsgogo, for some kind of interface stench connected to the computer.

SATA – disks are connected to the computer behind the same interface as the standard HDD. They look like stench disks for laptops and may be 2.5 inches wide. The mSATA option is larger;
PCI Express – are connected as primary video cards or sound cards at the computer expansion slot on maternity pay. I can see productivity and, most of all, be placed on servers at counting stations;
M.2 - Miniature option often for PCI-Express interface.

In today's accumulating SSDs, the main NAND memory is broken. For її type їх it is possible to subdivide into three groups, yakі vikal chronologically: SLC, MLC, TLC. What newness became the memory, then the superficiality of the middle ones became lower. Mistkіst with whom grew, which helped to reduce sobіvartіst. The reliability of the disk must be deposited under the robotic controller.

Not all SSD makers produce flash memory for their own add-ons. That controller vibrates its memory: Samsung, Toshiba, Intel, Hynix, SanDisk. Few people have a good feeling about the Hynix SSD drive. Vіdomy virobnik flash accumulators Kingston vikoristovuє memory and controllers firms Toshiba in their disks. Samsung itself is engaged in the development of technologies for the production of memory and controllers and completes its SSD storage devices with them.

SSD Specifications

We may have gotten rid of SSDs with accumulatives, so we didn’t have to talk about the characteristics anymore. Father:

Disk space . Sounding characteristic is indicated by the value of a non-multiple step of two. For example, not 256 GB, but 240. Otherwise, not 512 GB, but 480 GB. Why is it due to the fact that disk controllers reserve part of the flash memory to replace blocks, so they used up their resource. For a koristuvach, such a pidmina is unremarkable, and they don’t use the given wines. If you want to set the size of the disk to 480 GB or 500 GB, the flash memory itself on the disk is 512 GB, just different controllers reserve її different volumes.
Disc speed . A lot of SSD storage capacity: 450 - 550 Mb / s. Tsya value in vіdpovіdає boundary vіdkostі іnterfeysu SATA, yakim stink pіdlyukayutsya. The SATA itself is the reason, through the way the hacks do not work on a massive scale to increase the speed of reading. The speed of the entry in the appendices is significantly lower. Virobnik sound indicative of the characteristics of the very portability of the record on a clean nose.
Number of memory chips . Depending on the number of memory microcircuits, productivity can be deposited without interruption: if there are more of them, then more operations can be performed at once on one disk. In one line of discs, sound the speed of the record for the growth of the disc. It is explained by the fact that with more models, the number of memory chips is greater.
Memory type . More expensive is the better memory of MLC, less expensive is the cheap TLC, and Samsung's 3D-NAND is also good. Three times, remember, at the same time, most of the time they wink at the accumulators. Rich in why on modern solid-state disks, it is necessary to lie down as a controller.

Visnovki

Regardless of their similarity to a giant flash drive, SSD storage devices carry their own spectrum modern technologies zavdyaki why show a significant increase in productivity, without wasting arrogance. Working with a computer, after installing the system on such a disk, becomes much more comfortable.

Good afternoon. Corylist computers have long called out that internal hard drives are called HDDs. Ale, not long ago, hard disks SSD began to appear on the markets. A lot of people are rotten, but what is it, an SSD drive? Is it necessary to replace the original HDD with them? Why are solid-state drives so good, how can they be told about them?

What is an SSD disk

SSD - tse, as I have already stated, a solid-state drive. At this disk NAND memory is broken. Chim won’t stop, for memory, you don’t need electricity to save information. I can tell you my mind, which disk can be matched with a decent flash card. In fact, it's a flash drive.

I already wrote about flash cards for 1 TB and 2 TB. The technology is similar. From the same retail, for 1 and 2 TB flash drives, I wrote about what I wrote, just flash cards. And the SSD is a hard drive and can be decent enough to write and read data.

Vіdminnіst SSD vіd HDD and їх features

In order for us to be able to show the data of solid-state disks inside disks, with mechanisms that can rotate, let's talk about theories and robotic accumulators.

HDD - a series of round plates made of metal, which are wrapped around the spindles. Data are written on top of the plates with a special small head. As soon as a person starts copying information to the disk, or just run the software, the disk head starts to rot, in order to know those places where people need information.

The best guess is the zvichayny dresses of the Radyansk hours, as the meshkans of our country loved so much. And there is a head for reading data in this design.

Advantages of SSD over HDD

The SSD disk does not contain any necessary parts, as it would collapse.
Vihodyachi from the first point, the solid-state storage device does not heat up; folding program chi gra.
Shards of the disk do not collapse, they work silently. Just like that, bezshumnіst come out, through a small cooler for tightness, which is not obov'yazkovo cool down the disk.
Through the opening of the rotting parts, a little less electricity comes out, less than about twice.
Naygolosnіshe, podіbniy disc is more like a swidkukuetsya on a diyu people. Tobto, how do you install this Windows disk, start the computer will be faster.

I have presented to you the main advantages of SSD drives, which you can check for yourself. Ale, sho tsikavo, people dosі to put similar food and porivnyuyut forwards tsikh Zhorstky Diskіv:

Through the presence of crumbling parts, hard disks work without sound and the term of their operation is significantly greater. The primary disks break most of the time on their own through a slow call - solid-state disks should not cause any problems.
The temperature of the solid-state disk is constantly at the required level, regardless of whether the cooler is cooled down. A disk that is collapsing can become very hot without a fan. Overheating can lead to failures in the program or in any mechanical part.

Shortage of SSD disks

The head short of a solid-state disk is a hard disk. She will continue to get decent and may have a direct relationship with her. Another shortcoming of such a disc is less write / delete cycles. Rukhomiy Winchester can be overwritten and vmicati/vimicati even more times. Solid May at tsomu sensi obmezhennya. Prote, the data on the exchange in the records are practically important.

As a rule, the term SSD warranty is in the area of three to five years. Ale, in a wonderful life, such discs are significantly older. Zvіdsi, don't worry about what food.

Naytsіkavіshe, that is a hybrid, in the back part of a solid-state disk, and there are elements that are collapsing. The hybrid is called SSHD. The hackers in the SSHD disk tried to overcome two of the disks. Prote, high speed robots are afraid of less than an hour of zavantazhennya computer. Viewed information and record for this model is approximately the same as for a great HDD. These hybrid models are not particularly popular with people.

How to choose the right SSD disk

It is permissible, you have given a visa, that it is necessary to replace the morally obsolete hard drive and add an SSD drive. It became clear to you why SSD was a good idea to buy. Ale, є іnshe nutrition, zokrema, yak s SSD disks in such a way it is better to choose?

When you visit computer stores, Be sure to save up, yak may differ in controllers, form factors, prices. It is important to choose a day for all of your diversity. So, in order to make it easier for you to choose the middle of similar disks, I will set the parameters for which SSDs to use.

Speed of robotic disk

A skin hard disk, including a hard disk, has two types of hardness: reading information and recording. The greater the number of speeds, the greater the advantages. Ale, varto remember that in the descriptions of the hall it is most often written max speed.

SSD disk capacity

I already said that the main vada of solid-state disks is the whole varity. Call out to lie down in obsyagu disk. Min charge for today is 60 GB. In the current realities for Windows 10, with the usual updates, you may need 80, 90, 100 GB. Therefore, such an obligation can not be swiped on the system.

Ale, if you love to play games, and you will choke graphics programs For Photoshop, you need to convert disks with a capacity of > 120 GB.

Controller and Memory

There are three variations of memory, ie one type of one is introduced by the number of bits in the middle of the memory - 1 bit (SLC), 2 bits (MLC), 3 bits (TLC). Option 1 is old, you can’t stop yoga at once. Please note if you have a similar option in the descriptions of the disk, once you go through.

MLC is currently the largest extension. Yogo mi y oberomo. Wanting to have a new presence and minuses. Ale, now, replace it, you can’t, because TLC is only starting to check on the police at shops and the price of yoga is clear.

Shchodo controllers the problem is similar. The widest (popular) technology at the moment is SandForce, as it increases the speed of work and accumulates a way of squeezing information in front of it, as a koristuvach її write down.

Ale, and she has a short time: if the disk is filled with data more often, then, having cleared the disk, the speed of recording to a great pace will no longer turn around. In other words, now you will be lower. In order to solve this problem, it is necessary to remember one simple word: do not block the disk under the tie. At tsomu vpadku, after seeing the data, everything will be OK.

Understandably, there are other, expensive controllers with Indilinx, Intel, Marvell technologies. Analyze your finances, and even if you allow the stench, look at your SSD, some controllers of these vendors.

Form Factor Design

Most solid-state drives, which are being developed today, are being developed in form factor 2.5, which supports the SATA 3 design.

SSD old,
PCI card, as it is inserted directly into the system board slot,
Storage with mSATA design, which is installed in small PCs and laptops.

If you look at the design, then all new SSD installations have a SATA 3 interface, and if the controller of the old generation (I - th, or II - th) is on the system board, then a hard disk, regardless of whether you can plug it in. Prote, є obezhennya. The speed of data will be like that of the controller of the old generation. In other words, if you connect SATA 3 to SATA 2, the data will be SATA 2.

Since the 3.5-inch form factor is important for a PC, then if you want to install a 2.5-inch SSD, you need a transitional attachment, the title of "Sled". This adapter is similar to a small police, as it is necessary to move there, de wi can insert a disk.

To respect: vicorist special. The adapter allows you to install an SSD on the laptop DVD space. Part of the coristuvachiv tidy up the drive, which is not enough vikoristovuetsya at a time, and install an SSD disk on the same place. People install Windows on a new disk under the house. The original hard drive of the laptop can be formatted and stopped to save special information.

Which company to choose SSD, choose

Tse nutrition vimagaє sawing respect. Zrozumіlo, on rich forums you will find posts about those that are better than Silicon Power, otherwise say Kingston. These firms vibrate discs of various types.

But we don’t call it that way. Virobnikov, as if it were true that NAND flash memory is being used, it’s not really rich, it’s for branding.

You can also choose companies: Samsung, Crucial, SanDisk.

How to practice with accumulating SSD

As soon as you have successfully installed the SSD disk, you start the system and you will be well received swedish robot all programs, and addenda. The system will also start up quickly. In order for the computer to work so quickly, remember how to operate the SSD storage devices.

Do not fill up the accumulating money until the last day, before the eyelids, otherwise, as I have already said, the speed of recording data will become less and, at least, it will not be possible to remember. SandForce is especially valuable.
Operating systems that support TRIM, є: Widows 7, 8.1, 10, Linux 2.6.33, Mac OS X 10.6.6.
Wart save special information on HDD. It’s not easy to get rid of such a disc, like wine at a miraculous camp. Insert two disks, and on the HDD record video, audio, photo and other information, for which you do not need high speed.
It is necessary to increase the capacity of the operational card and, as well as the possibility, not to varto win the download file.

Following these recommendations, you have a chance to continue the speed of operation of the SSD drive, while not failing yoga and not reducing the speed of your work. You can get yoga on Aliexpress. Disks on the side with a volume of 120 to 960 GB, which is actually 1TB. You can come for help.. Judging by the description, the disk is supposed to be both for computers and for (notebooks).

According to the screenshot, you can download disks. If you need to install a system, bring a disk with a capacity of 120 GB. Well, as a full hard disk, then, in your opinion, 480, up to 960 GB. Why am I happy to install Windows itself on a hard hard drive? Your system will take advantage of you in a few seconds! If you bring a 1TB disk, all the programs you have will be slow!
