Let's hurry to the robot with a full flash drive. Files are copied to a USB flash drive in full: what is the work? Why is the speed of transmission via usb 3.0 falling?

Portable flash drives today are the most popular compact data carriers. Optical disks are already practically out of mass adoption, and modern hard disks and SSD-accumulators, for their size and superiority, are still not able to compete with flash drives. Flash drives are small, handy and can hold a lot of information, but there is one thing - the speed of recording on a flash drive is significantly lower, the speed of recording on the same SSD or HDD. In addition, after a trivial victorious flash drive, it becomes a little bit more. Chi can you speed up the flash drive, so that you can record it if you want a little bit of shvidshe? So, there are a few ways, how you can increase the speed of recording on a flash drive.

Accelerate way to improve productivity

Vіdkryte vіkno vіkno vіkno vіkno vіkno vіkno vіlnosti flаsh kopichuvacha ta і sovlettsi Ownership select from the list of attachments the name of the flash drive. Let's press the button power.

After that, at the end of the day, the powers that be accumulated, go to the tab Politics and install a jumper on the item Optimum productivity.

Please note that after setting this parameter, the write cache for the flash drive will be activated. Therefore, when you turn on the accumulating data, it is necessary to vikoristovuvaty safely vyluchennya, otherwise you risk spending files on flash drives.

Sorry for help formatting

Another simple way to speed up a flash drive is to format it in another file system. For which, in the context menu of the flash drive, select the item Format, and in the format parameters, specify as the NTFS file system.

Before Tim, like a rozpochati formatuvannya, varto vrahuvat sche two important moments. First, formatting must be done outside, so you need to uncheck the box Shvidke (purified zmist). And in another way, to achieve the best result, you can choose the size of the cluster. If you plan to write mostly large files to a flash drive, then select the maximum size of the cluster, if you write a lot of small files, then set the size of the cluster to be small.

Adjusting the speed of the controller

The third way is collapsible, the shards are transferred to the robot with BIOS settings. For this implementation, you need to go into the BIOS interface and find out the partition that is responsible for setting up the USB. As a rule, the division is called USB Configuration. If you need to know in the next section the item under the name USB Controller Mode and set it to a new value full speed or HiSpeed.

Calling on those who are given ways to transfer the introduction of some changes to the file system, accumulating or in the BIOS and flash drives, stink, maybe, not all of them. If you have a stable and reliable practice of flash storage in your first place, as well as saving data on a new one, it’s better to deprive all of the settings like that. And if you are standing in front of you, be sure to speed up the USB flash drive, resurrect more to come more quickly.

Run out of food? - We are FREE to wear on them

After buying a new computer, and it became three times more than that, with the connection of all peripheral devices, I turned my attention to non-primary USB sockets. The stench of the boules of blue color:

As it turned out after the receipt of information from my motherboard - for USB 3.0. At that time, I didn’t know anything about the standard and started looking for information on the Internet. Information about the USB 3.0 standard is rich, and super friendly. Axis scho about the new write Wikipedia:

The USB 3.0 specification offers a maximum data transfer rate of up to 4.8 Gb/s - which is much more than 480 Mb/s, which can support USB 2.0. In this way, the speed of transmission increases from 60 MB / s to 600 MB / s and allows you to transfer 1 TB not in 8-10 years, but in 40-60 hvilin. The USB 2.0 cable can be mixed with two lines - a pair for receiving / transmitting data, Plus and zero eating. In addition to them, USB 3.0 adds another line of connection (two twisted bets), as a result of which the cable becomes richly comrade. New contacts in USB 3.0 sockets are re-stamped like the old ones on the other contact row. Now you can easily determine if the cable is up to the current version of the standard just by looking at the rose.

Literally, more accurate than the previous ones, read by me. I guess you can say that USB 3.0 is the new transmission standard, because. appearing in 2008 roci. Vіn vіdіznyаєєєєєєєєєєєє from the front head rank swidkіstu and more from 500 mA (USB 2.0) to 900 mA strum zhivotnja pristroїv, scho connected. In this case, the retailers saved the wholesomeness of USB 2.0, and I can say that when the USB 2.0 flash drive is turned on in the USB 3.0 socket, the won (flash drive) is recognized by the system as richly swidshe, lower when the USB 2.0 socket is turned on in the "red" socket

The maximum read/write speed of USB 3.0 is 600 MB/s, but in practice it can only be reached when a portable device is connected. With the exception of traditional hard disks and flash drives, the average speed of reading will be 70 MB / s, and recording 30-60 MB / s (false depending on the model). Tse vіdbuvaєtsya through povіlnі: disk mechanics and flash storage controller. But all the same, it’s 2 times better than the best-width USB 2.0 flash drive, so the new standard is savored by those who often have to copy data onto a hard drive or a flash drive.

The speed of data transmission grew not only through the implementation of new methods of data transmission, but also for the modernization of conductors and connectors. You can see in the image that the USB 2.0 port will cover the lines. Two lines in the center are for data transmission, and the extreme ones are zero plus for life.

The new USB 3.0 connector has more lines added, as well as a cable for the USB 2.0 line, and a new cable has three comrades for the front. Yogo can be easily adjusted without color marking for the number of contacts in roses.

An increase in the stream of life up to 900 mA solves the problem of such attachments as hard disks, such as when connected via a cable or a USB hub, often there is no voltage through the cables and additional sockets.

This standard did not gain a wide width to the fact that Intel Corporation decided to introduce USB 3.0 in its chipset until 2011. And yet the troubles are obvious in the last hour, with the advent of HD-video and SSD-carriers, it is becoming more and more relevant. The features of USB 2.0 are no longer up to the mark.

How to solve the problem with more copies of data on a USB flash drive?

Let's look at the broader causes of these problems and let's talk about the ways to overcome them.

1. Flash drive performance

As with the computer, everything is harazd, the culprit of the full process of transferring files to a USB flash drive, obviously, stay. Budget flash drives, as a rule, cannot boast of a great data recording speed. I speed of 5-7 Mb / s with a USB 2.0 connection interface can be a normal thing for them. You can protest the speed of recording data on a flash drive with the help of Windows-programs for testing the speed of hard disks, and with the help of the popular utility CrystalDiskMark. More than that speed, which the tests of the flash drive will show, do not judge it for real.

2. USB port of the computer

A USB 3.0 flash drive will work just as well as a USB 2.0 flash drive, as long as this interface is supported by a computer, and USB 3.0 will not. The USB flash drive is interchangeable with the security of the robot port. In order to optimize the productivity of the USB 3.0 interface when copying data, the stench is due to the possession of the USB port of the computer. The situation is different if USB 3.0 or 2.0 is connected to a USB 1.0 port. About those, that the flash drive is connected to a low-width USB 1.0 port, Windows, as a rule, immediately reminds you of system notifications: if you can use it, you can use it more quickly, so that you can connect to a USB 2.0 port.

If data is adequately copied to a USB flash drive, if it is connected to the USB port on the front panel of the PC case, you can protest the speed of the robot in the minds of connecting to the USB ports of the motherboard on the back of the case. It is possible that USB 2.0 or 1.0 ports are placed on the front panel of the case, while ports of the motherboard transfer USB 3.0 or 2.0 interfaces.

Similar to USB-ports, which can be used to record data, to save files, USB-support can be used. Just like a USB port transmitting a USB 2.0 interface, it will use its boundary bandwidth to encircle the security of the robotic USB 3.0 interface of a flash drive and the USB port of a computer.

3. Weak hardware stuffing computer

On old or budget models of computers, more data can be written to a USB flash drive, but with a weak hardware filling, a small amount of operational memory, or a more powerful disk. At this time, it is better to upgrade the computer.

4. Drivers

More copying of data to a USB flash drive may be due to incorrectly installed USB drivers. In this case, you can either update the motherboard drivers or install the USB controller drivers. Updating the drivers of the motherboard can be carried out manually, by arranging the installers from the official website of the payment for a laptop, or you can entrust the right to special programs - drivers installation managers. Among these: DriverMax, Auslogics Driver Updater, SlimDrivers, Advanced Driver Updater, etc.

To reinstall the drivers for the USB controllers, open the Windows Attachment Manager, open the "USB Controllers" box and the additional option "Visibility" in the context menu of the skin add-on and see the driver in the list.

Drivers for USB controllers are installed automatically.

5. Customized BIOS

For some devices, it is possible to write data to a USB flash drive with a little bit of security and USB-ports in the updated BIOS. Such an exchange is necessary, as a rule, at the distribution of the BIOS Advanced patches. If the USB 2.0 Controller Mode parameter is set to Low-speed, you should change it to Hi-speed.

6. How to speed up writing data to a USB flash drive with software tools

As the reason for the problem lies in the low speed of recording data on the flash drive itself, unfortunately, it is not possible to speed up the process of copying files onto it. Navit as a productive computer. By software tools, the speed of recording files can be reduced to less than a trio.

Like a flash drive, you need to copy a small number of other files, it's better to combine them into one archive file. Place this archive file on a USB flash drive. One important file is copied faster, lower mass of others. Before speech, when copying small files, productive USB storage devices can "pass through".

You can also speed up the transfer of files to a USB flash drive with the help of special programs that work with regular Windows copyers as a part of productivity for the work of the master algorithms for copying data. One of these is WinMend File Copy, which can be downloaded free of charge from the creators' website www.winmend.com/file-copy.

WinMend File Copy has a Russian interface, supports packet copying of files, adjusting the buffer, and also redirecting the transfer from the opening space.

So far, I have not been able to describe the USB port robot. This time I want to stick with those USB robotic sweds. All current laptops and desktops are equipped with USB interfaces. You can increase the number of connected outbuildings up to a few dozen for the help of so-called hubs. Also, it’s an extension, like all the same for USB robots, for example, mouse and keyboards, and the axis of accumulating memory (flash drives and hard disks) can also be stored according to these parameters. Well, when transferring files to a disk, connecting via USB, it’s small, but good.

How about, how well does the USB port work? In this situation, I prepared a few reasons to describe the problems, as well as solutions to help speed up the USB robot. I support you, I can help you.

Reason #1 - Old USB Types

Here, on the spot, that a port has been installed on your outbuilding, which can be seen to the old specification. There are three types of ports available: USB 1.0, USB 2.0, USB 3.0, and another USB 3.1 version.

Between these two versions, obviously, there are a lot of details, but mostly it is due not to the old look, but to the swedishness of the work.

Obviously, the most common is USB 3.0, with more meanings in blue color, it will be easy to confuse it with other versions. So I want to guess what, if you can attach, say, a hard drive, some kind of building practice on USB 3.0 security, and if you connected yoga to port 2.0, then it’s not possible to use it with maximum capabilities.

And the axis is a couple of parameters of the skin port:

USB 1.0

• Maximum speed 12 Mb/s;
• Length of cable Max 5 m;
• Number of connected extensions Max - 127;
• Life pressure - 5 tbsp.

USB 2.0

Knowing the standard changes, you can find out about them below.

• Maximum transmission speed 480 Mb/s;
• For keyboards, mice and joysticks, 1.5 Mb/s is enough;
• For audio and video devices - up to 12 Mbit/s.

USB 3.0

With this standard, it is possible to choke the transmission speed up to 5 Gb / s, and with the vinicated version 3.1 up to 10 Gb / s. Thus, the possibility of a one-hour transmission appeared, and that acceptance of data, which increased the speed of work. May the great power of the strum, which helps to connect without problems whether it’s hard disks, as well as to charge devices more quickly, for example smartphones. USB 3.0 can be confused with the previous standards.

What do you need to grow? Raju get a PCI controller, a little lower.

What port to stand on a laptop or computer?

About tse I have already written a report. Ale, there are a few moments, which are not included in that article. In the first place, you can tweak the documentation to your system board or laptop and find out everything in the technical specifications.

Another point is the selection of special programs, which will show you all the technical and software characteristics of the computer.

Like a butt I’ll direct a utility AIDA64, Oskіlki himself often koristyus. You can get a trial version from the official site. Otzhe, let's go to the distribution "Attachments" and there we select the item "USB Attachments", right-handed you sing all the spoils, like your computer.

Reason number 2 - the maximum speed is enabled in the BIOS

Buvae th so. As noted that the speed of USB 2.0 was suspected to be low, then I know there is a fix, connected with USB. You can change the stink at the depositor Advanced. There you can switch the setting to Hi-Speed or full speed. I can’t tell you exactly, because on different BIOS versions the parameters are defined differently.

Reason #3 – USB port daily

In today's laptops, those motherboards are practically impossible. If I wanted a couple of USB 2.0 ports, it would be ok. Obviously, as you have a different situation, you can easily get a controller PCI USB, for example, versions 2.0 or 3.0 or all at once. For the price the stench is not dearer. For example, you can find a USB 3.0 controller for a price of 700 rubles.

Installation is also simple. Golovne nobility, as if looking at the PCI slot. Before Tim, how to work as a child, obov'yazkovo turn off the PC and pull it out of the socket. Further, you can pull the cover of the system unit and change the correct PCI slots, because of the stench, then insert our controller there. After the computer is upgraded, it is still practicable, it is necessary for the software to be installed automatically.

Reason number 4 - the speed of work on the level of USB 1.0

Blame such a problem. In this case, you can inspire such a reminder: "USB-attachment can be used more…". What can I say about those that you have on your PC?

If you note that USB 2.0 or 3.0 is on the same level as 1.0, then wine can be used in that. You may need to upgrade to the remaining versions, or delete it, and then reinstall the system. Fight like this:

1. We go to the extension manager - keys Win+X ta vybіr vidpovіdnogo item;
2. Open tab "Controller USB";
3. On the necessary extension, we press the doors, and then we go to the tab "Driver", de tisnemo "Vidality".
4. Click on the tab "Diya”, and then we select the item "Update configuration".

Also, there is one nuance for an hour of copying files. The speed will be richly lower, so you copy a lot of files in a smaller size. If you want great speed, put these files into one archive.

USB 3.0

Day by day, we are happy with the success of the victory and the mittevu connection of USB devices. Hello, we just curse the interface. USB with plug and play technology Ale іnodi, vіn nіbіv vіn nіbіv vіdmovlyаєєєє vyznati pristrіy or zabezpechuvati that shvidkіst work with him, on yak mi ochіkuvali.

USB 2.0: similar, all day long.

With the advent of chipsets Intel somoї series and AMD Fusion Controller Hub, which support USB 3.0 It is important to note that we could correspond to the first generations of the USB interface more than ten years ago. The maximum bandwidth was 1.5 MB / s, and files were transferred via USB 1.1 even more regularly, the situation was often disturbed by a small amount of USB storage devices.

Through some years of our experience, we have introduced updates to the USB 2.0 interface, which is the maximum declared transfer speed of 60 MB / s - the greatest stream in the USB 1.1 port. Tim is no less, the new interface was between the protocol and coding 8/10 bits, as a result, the real speed of transmission from USB 2.0 was in the range of 30-40 MB / s. At that hour, what was enough. As the popularity of affordable out-of-the-box RAID storage and SATA-based SSDs grew in popularity, we became more responsive to productivity, and bit by bit it turned out that USB 2.0's speed was starting to fail.

USB 3.0 Satisfying our needs in the interface with more high throughput building, the maximum indicator of such a connection is 625 MB / s. To change the signal transmission factor, we will take 500 MB / s. But looking at the price, productivity is real, it seems that it doesn’t reach such a high level, as it seems in the optimistic throughput charts, as the post-workers of motherboards love to place their products on the boxes.

USB 3.0: Best. Ale mi check for more!

On the basis of the speed of robotic flash drives and old hard disks, as in our laboratory, we were afraid that the speed claims would not be within reach. Tim is no less, we proceed to the wedding of the robots USB 3.0 And we will try to understand why it is possible to increase the speed of transmission over the cim interface.

USB 3.0

Why are our annexes on the base USB 3.0 chi pratsyyut approximately 150 MB / s on the speed, if the maximum number of applications for the interface is 500 MB / s, or close to that? In order to understand the internal USB attachments, it is necessary to understand the basic security and life.

USB dongles are not suitable for transmitting non-modulated data, the information must be encoded with a line code, and then decoded in a different way. This is an important moment, which allows the parties, which accept, to restore synchronization. Without any pardon, the transfer will be richer. As well as a lot of other interfaces (for example, optical Gigabit Ethernet), USB vikoristovuyu overline coding 8/10 bits, which translates eight-bit data into ten-bit data, thereby reaching the bandwidth on the fronts of signal transmission. If you want to encode 8/10 bits, you will ensure the necessary synchronization of the stream, reducing the speed of transmission of core information by 20%.

Therefore, the speed of data transfer USB 3.0, to become 5 Gb / s, it is converted to 500 Mb / s of peak bandwidth. But this is not the only factor that makes the transfer really fast.

At the characteristic USB 3.0 on the USB Implementers Forum (USB-IF), under paragraph 4.4.11, the following is mentioned:

The performance of SuperSpeed ​​USB depends on a number of factors that include 8/10 bit character encoding, packet structure and framing, flow control and protocol override. At a transmission frequency of 5 Gb/s with coding of 8/10 bits, the net throughput is 500 Mb/s. If flow control is violated, the packet structure and the protocol override, the throughput of core information to become 400 MB / s or more.

Raptom swidkist USB 3.0 spent more than 100 MB / s. However, 400 MB / s seems to be doing badly in 40 MB / s for a USB 2.0 interface.

Irrespective of those that these numbers help to streamline scoring USB 3.0, the stench does not count on food, which is why the real signs of the flooring are lower. We, like before, feed, why attach with an interface USB 3.0 so povіlnі, if in the characteristics it is assigned a lot more throughput capacity?

In a first step, the controller of the building itself will also contribute to productivity. On the graph, the Thermaltake BlacX 5G is clearly slicker, the lower Apricorn SATA-to-USB 3.0 Adapter, for example, you can only look at the high performance SSD. More hostile to those that the BlacX 5G can outperform the current RAID set in Buffalo, the result of some indication on the first chart. Of the three applications, there is only BlacX 5G vicorist controller ASM1051. Vykhodyachi from our dosvidu, add what they support USB 3.0 and beat the ASMedia controllers, ensure the highest level of productivity. But one thing is not enough to get through the 300 MB / s barrier and reach the peak performance of the interface.

In another way, the interface controller itself has a great impact on the throughput. Visionary tests were carried out on "native" ports USB 3.0 maternity pay ASRock Z77 Extreme6. In view of the above, there were super-clear indications of productivity, and the result, it seems, lay behind the specifics of the implementation. The Etron controller on one board secured 250 MB/s, and the same controller, but on another platform, could not cross over 200 MB/s. Prote, in general, the cost is most related to the USB Platform Controller Hub or the Fusion Controller Hub.

І rest, no matter what the interface USB 3.0 building security of 400 MB / s, which has the potential to develop an inefficient protocol. All types of USB include several types of transfers: control, transfer, isochronous and linear transfer. The first two types of Control and Pererivannya signify how the host connects to the outbuildings. The third type is isochronous transmission, which is necessary for periodic and continuous transmission of data, it does not matter, as it can reserve a certain amount of bandwidth with a guaranteed shutdown. Isochronous transmission sounds victorious in audio / video attachments such as flooding cards, shards won't solve the problem of wasting data (waste of frames in video), if vicorating a splint is connected via USB. And now, the mode of bulk (linear) transfer (bulk-only transport) is the most important for us today, so we have to win for transferring data to USB-sources.

Bulk-only transport technology, abbreviated as "BOT" in engineering teams, was expanded in 1998 for USB 1.1 as a protocol that accepts and processes one command at a time. BOT technology was specially conceived for the needs of USB flash drives, as at that time there was a small amount of data. At the link with zim, BOT is similar to IDE in that the number of commands is processed on the host (which explains why USB productivity decreases with greater depth of charge).

The "BOT" technology has lost the permanent USB 2.0 interface, which debuted in 2000, but only through those that the very portability of the USB bus is a "narrow space", and there is no sense in the BOT update. Ale, in retrospect, it may not be so, because USB 3.0 it’s not better anymore, it’s lower, it’s better to come up to the new one.

USB 3.0 Turbo Mode

The maximum transaction size for BOT-transfers should be set to 64 kb on the same operating system. However, the last data is transmitted in blocks of 128 kB, for which two BOT transactions are required. The technology, called Turbo mode, helps to improve the exchange by increasing the maximum transaction size to 1 MB or more, allowing the USB driver to pack a 128 kB batch of subsequent requests into one large transaction. The smallest number of small transactions means fewer USB commands to be cleared, prepared and confirmed, which has more throughput.

With the Turbo mode function, USB 2.0 speed increases by 8-10 MB / s and productivity increases by ~ 25-33%. The increase will be independent of the fact that you have a great hard drive or SSD, so that the speed of the robotic accumulating power is for the bandwidth of the interface.

If you have one of these Asus motherboards, then in the Asus utility USB 3.0 Boost order after the Normal button appears either the Turbo button, or UASP at the moment, if the port USB 3.0 priednano vіdpovіdny pristry. It doesn't matter which port is chipset, or it is serviced by an ad hoc controller. Turbo mode is typical for any USB 2.0 devices or USB 3.0 without UAS, and as your attachment, connections through USB 3.0, support UAS, then Turbo mode will not be available to you. After locking, for all attachments, the Normal (BOT) mode is restored.

The ASRock XFast USB program seems to be more polished and turns on Turbo mode on any USB port, so it can still be loaded up to a new storage, not yet formatted by NTFS or FAT. Prote, only Asus allows you to enable the UAS protocol in Windows 7 with the help of a licensed driver MCCI ExpressDisk UASP Driver .

The Asus UASP driver is shorter, lower BOT and the "old" UAS driver in Windows 8, especially with the foreground read operations.

During the last transfer of data, the Windows 8 UAS driver appears faster and safer at 360 MB/s, outperforming the Asus UASP driver by 25 MB/s in read operations. For equalization, the maximum for BOT is ~300 MB/s. The Asus UASP driver is the leader in the last record with ~340 MB/s speed. Windows 8 UAS driver is less than ~325 MB/s. Ale offending the UASP modes, it will be possible to reduce the number of times the BOT is reduced, the maximum of which can be ~ 315 MB / s.

USB 3.0 Enable UAS on older motherboards with USB 3.0 support

As we have already planned, to build it as you have attachments, which supports the UAS, the system, in which you install it, is also guilty of supporting it, otherwise there will be no sense in it. For whom you need to insure hardware and software factors.

Windows 7 driver set does not include UAS support, so Asus utility USB 3.0 Boost may have configuration inf files in the setup subfolder. Qi files are an insufficient link.

As it turned out, technically you can tweak these drivers to enable UAS manually. However, on this way there is one pereskoda. If the Asus company licensed the MCCI UAS driver, it added a subprogram to check the selection of your motherboard model. If you change the fee for your company, everything will be folded up at once (though in our laboratory we have worked out the prac- tication utility).

Also, if CPU-Z recognizes your motherboard vendor as "ASUSTek Computer INC", manually change "USB Mass Storage Driver" to "ASUS USB 3.0 Boost Storage Driver" at the system authorities and add another "UAS Storage Driver."

Trying to work out the focus on the board is not available to Asus until the announcement of the pardon. The only way to get around this is to modify the SMBIOS row with the help of a special utility. Well, I know, it’s not like the skin wants to fiddle around, especially as a lie, but not the whole procedure.

It’s enough to reconsider, we took the old Asus board, ya can USB 3.0, but do not support UAS.

hardware part

Just because the driver installs doesn't mean that UAS works. Also, you need a portable equipment support. Take as an Asus P8P67 Deluxe stock. Understandably, there is no way to avenge the necessary row of SMBIOS, but the Renesas controller gets used to it USB 3.0, so the model is not shown in the list of boards, so please support USB 3.0 boost. You must pay for this list to have one warehouse warehouse - the controller ASMedia ASM1042.

On the right, the ASMedia controller supports UAS, while Renesas does not. We were able to get rid of UAS through the "native" port USB 3.0 Z77 chipset for Windows 8 help on the ASRock Z77 Extreme6 motherboard (order with the Asus UAS driver on the P8Z77-V Deluxe motherboard with the Z77 chipset), not to mention those that the Intel controller supports the UAS protocol.

For the old Renesas controller, there is no necessary hardware support, or the driver needs to be updated.

Imovirno, it would be easier to buy a card Syba USB 3.0 PCIe (SD-PEX20112). The cheaper solution is to work through those that are based on the ASM1042 controller, which supports the UAS protocol. Just install the ASM1042 driver from Asus and you're all set to go.

Test run Iometer on Thermaltake BlacX 5G connected via Syba card USB 3.0, support the work of UAS The speed of the last reading reaches 325 MB / s, such an indicator we wanted to work on the board from the "native" support of UAS.

USB 3.0 On the way to greater productivity

Productivity USB 3.0 strongly kolivaєєєєєєєєєєєє in zalezhnosti vіd kontrollerіv, pristroїv that host, about tse to check the data of our tests. I want to know if the combination of components will give the best result, just to carry out the follow-up.

Turbo mode and UAS - two advanced technologies to improve cob behavior USB 3.0. And for both solutions, you will need an extension, so as not to "zadatimut" productivity and let the interface open up completely. Connect external hard disk via USB 3.0, and in practice on the same speed, it is practical in any situation. Shchob diysno vіdchuti raznitsyu, nebhіdno vikoristati shvidkіsny solid-state accumulator.

Ale, do not rely on the increased speed of robotic and vipadkovy input / output operations. We seem to know that a lot of people pay for accumulating, connecting via USB and working out of tasks, as they carry out a large number of operations with different data transfers, and I want to pay attention that Turbo mode and UAS will not help you. In fact, only linear read/write operations can take away the increase in speed in these modes.

Possibly, marvelously, but the biggest increase in swidkost zavdyaki Turbo mode we ran on outbuildings USB 3.0, yakі demonstrated the lowest level of productivity Adapter Apricorn SATA-USB 3.0 Adapter - our favorite lab tool - Vykorista nasty optimizations controller. Bagato cheap USB 3.0-Shishishcha and flash-accumulators are used in this category, and in the same way, attachments play the most in Turbo, and it’s good, Turbo mode shards are not costly.

However, turn on the Turbo mode, if you win more expensive extensions on the base USB 3.0, like, for example, Thermaltake BlacX 5G, because the performance of the standard mode (BOT) is good. In this situation, it is very different from UAS, depending on your system, the speed of the subsequent transmission may be 20% higher.

UAS is a remarkably new technology, so we try to avoid it in any case. Deyakі z postachalnіv, with whom we contacted, said that in their laboratories the stench took away more high results, and we can imagine that verity. According to the words of deyakyh іnzhenerіv, with new additions, which are being developed, the speed of the last operations reaches 430 Mb / s, and those of the vipadkovyh - 100 Mb / s. For the sake of equalization, on our setup, we were able to take 350 and 70 MB / s normally.

Well, the UAS interface has great potential, and enthusiasts can't be the only one who takes a lot of wins. As one of the engineers of Western Digital, this technology is more relevant for mobile systems and desktop systems of a very low level. When working in BOT mode, USB strongly affects the central processor, and does not explain why USB 2.0 and USB 3.0 more often pratsyyut povіlno on older systems. The UAS protocol is efficient and gives significantly less CPU overhead. Addition of support for the roughness of the commands opened the door for increased productivity, the shards of the operation are processed in parallel. All the same, as a result, it helps to improve productivity on old and cheap computers, robbing the processor for other tasks.
