USB 3.0 real data transfer speed. How to speed up a slow flash drive

Every desktop computer, laptop, tablet and any other gadget has USB ports. If port speed is not important for devices such as a keyboard and mouse, then for the operation of flash drives, removable hard drives and cameras it is one of the important indicators. If the port is slow, then transferring files from one device to another takes a long time. To correct this situation, you need to know some features of USB ports.

USB port specifications

Today there are three USB types-ports:

• USB 1.1;
• USB 2.0;
• USB 3.0 (3.1).

The speed of their work is different. In this case, you need to take into account the speed of connected devices, which also have their own parameters. For example, if you have a flash drive with a USB 3.0 connector, and your computer has USB 2.0 ports. The flash drive will not work faster than the speed stated for port 2.0. This technical features devices that can only be changed by replacing the PCI controller.

As for the technical characteristics of USB port 1.0 and 1.1, they are as follows:

• Two modes of information transmission, namely with a high throughput of 12 Mbit/s and a low throughput of 1.5 Mbit/s.
• The maximum cable length for data transmission in high-bandwidth mode is 3 m. For low-bandwidth mode - 5 m.
• The maximum number of connected devices is 127.
• It is possible to connect a device that operates in modes with different bandwidths.
• Voltage for peripheral devices– 5 V.
• Maximum current – ​​500 mA.

The USB 2.0 port differs from its predecessor in the following parameters:

• Implemented HiSpeed ​​mode 480 Mbit/s.
• Speed ​​for interactive devices is 10-1500 Kbps.
• Speed ​​for video and audio devices is 12 Mbit/s.

USB 3.0 (3.1) port on this moment is the most popular and fastest. Among the advantages of this port it is worth highlighting:

• Data transfer speed is up to 5 Gbit/s.
• The controller is capable of sending and receiving data simultaneously. In this case, data exchange does not affect the speed of the port.
• It has a higher current strength, which allows you to connect external hard drives to your PC, mobile devices, and even monitors.
• Well compatible with UBS 1.0 and 2.0 standards.

How can I check which port is installed on my computer?

The first and easiest way to find out your USB port type is to look in the documentation for your PC. However, if you don’t have it, follow these steps:

• Download the program AIDA, Everest or any other. We will use the first software. Launch AIDA on your PC.
• In the menu, select “Devices”, select “USB devices”. A list of USB ports will appear in the right menu.

• Thus, we have established the number and type of ports that are available on our device.

Ways to solve the problem with slow USB ports

If your PC supports a USB 2.0 port and you connect media with the same bus type to it, but the data transfer speed is negligible, it’s worth checking BIOS settings. Often it can be disabled in BIOS maximum speed for ports. To check this parameter, perform the following steps:

• We reboot the PC and exit into the BIOS by pressing “Del” and “F2” (the login buttons are different for each motherboard model).
• Go to the “Advanced” section (depending on the motherboard model, it may be different) and look for the “USB Controller” setting. Select the port and set it to “FullSpeed” or “HiSpeed”.

• Save the result with the “F10” button and boot in normal mode.

If your PC does not have a USB 2.0 port or you want to add 3.0, you will need to buy a special PCI USB 2.0 or 3.0 controller. Such boards are relatively inexpensive. You can install the controller yourself. To do this, you should perform the following steps:

• Turn off the PC;
• Opening the side cover system unit;
• We connect the board to the PCI slot. We fix the board to the front or rear panel of the PC using a screw.
• Turn on the PC and install drivers for the new component.

It is also worth noting that low speed Port malfunction may be caused by damaged or missing drivers. In this case, a message may appear: “This device may run faster...”. To fix this situation, you need to update your drivers. You can do this through the device manager by right-clicking on the controller, which is displayed with a yellow exclamation mark, and selecting “Update driver.”

After rebooting the PC and reconnection the problem will be fixed unless you have connected USB flash drive 3.0 to USB 2.0 port.

Finally, it is worth noting an important point. When copying small files, the data transfer speed is significantly reduced. This is due to the search for a free block on the disk for each file. To speed up copying, it is worth compressing these small files into one archive in advance.

Portable flash drives are the most popular compact storage media today. Optical discs have almost gone out of mass use, and external hard disks and SSD drives are still not able to compete with flash drives in size and reliability. Flash drives are small, convenient and hold quite a lot of information, but there is one point - the write speed to a flash drive is significantly lower than the write speed to the same SSD or HDD. In addition, after a long time of use, the flash drive becomes a little slower. Is it possible to somehow speed up the flash drive so that it writes at least a little faster? Yes, there are several ways you can increase the write speed to a flash drive.

Speed ​​up by improving performance

Open the properties window of the flash drive, and in the tab Equipment Select the name of your flash drive from the list of devices. Then click on the button Properties.

After that, in the drive properties window that opens, go to the tab Policy and set the switch to the item Optimal performance.

Please note that after use this parameter Caching of entries for the flash drive will be activated. Therefore, when disconnecting the drive, you must use “safe removal”, otherwise you risk losing files on the flash drive.

Speed ​​up with formatting

Another simple way to speed up a flash drive a little is to format it in a different file system. To do this in context menu flash drive select Format, and in the formatting settings window, specify NTFS as the file system.

Before you start formatting, there are two more important points to consider. Firstly, formatting must be done completely, that is, you need to uncheck the box Quick (clear table of contents). And secondly, to achieve better results, you can also choose the cluster size. If you plan to write primarily to the flash drive large files, then choose the maximum cluster size; if you write a lot of small files, then set the cluster size to small accordingly.

Controller speed setting

The third method is more complex, as it involves working with BIOS settings. To implement it, you need to go to the BIOS interface and find the section responsible for USB settings. As a rule, this section is called USB Configuration. After this, you need to find in this section an item called USB Controller Mode and set the value in it FullSpeed or HiSpeed.

Due to the fact that these methods involve making some changes to file system drive or in BIOS settings and flash drives, they may not be suitable for everyone. If your first priority is the stable and reliable performance of the flash drive, as well as the safety of the data on it, it is better to leave all the settings as they are. But when you are faced with the task of speeding up a flash drive by any means, the above tips will come in handy.

Still have questions? - We will answer them for FREE

Work on the USB 3.0 standard specifications was completed at the end of 2008, which enabled the computer industry to begin developing devices. Already in 2010, almost all leading manufacturers announced systems with USB support 3.0. But the massive onslaught of the new interface on the market is still ahead.

According to In-Stat, by 2014 the vast majority of new computers will be equipped with USB 3.0, and in 2015 - all without exception.

But this is only one side of the coin - after all, devices are also needed. However, it won’t be up to them.

If in 2012, according to In-Stat's forecast, less than 500 million USB 3.0 devices will be sold, then in 2015 - already 2 billion! By the way, I wonder where USB 1.1 devices are sold - judging by the forecast, they are reluctant to give up their position.

What's in my speed for you?

Have you heard that USB 3.0 can be 10 times faster than its predecessor? This figure is obtained by comparing its maximum throughput of 5 Gbps and 480 Mbps for USB 2.0. Device manufacturers, however, do not fall into marketing hysteria and indicate more real numbers, thereby avoiding accusations of deceiving buyers.

So, for my USB 3.0 flash drive it is modestly indicated that connecting to such a port makes it twice as fast.

Specific read and write speeds are also included, and below you'll see how they matched my tests.

Are you ready for the test? Always ready!

The actual data transfer speed depends on both the USB device and the system hardware configuration and USB controller driver.

The tests were carried out on an HP Pavilion dv7-6053er laptop (Windows 7 SP1 x64), where USB 2.0 and 3.0 ports are located on different sides. For the USB 3.0 controller, the driver was installed from using Windows Update.

In fact, this is an NEC chip and driver, since Renesas Electronic is a joint venture of several large Japanese companies, where NEC is the main shareholder.

I measured the speed of common household devices - flash drives. The star was the austere-looking ADATA S102 16 Gb (USB 3.0).

Backing up is the weightless and feminine Transcend JF620 32 Gb (USB 2.0)…

... and the big, brutal Sandisk Contour Cruzer 8 Gb (USB 2.0).

The pictures deceptively hide the true size of the flash drives, so I decided to reach for the camera.

USB 2.0 speed test

I used CrystalDiskMark for the test, and the first thing I decided to do was compare the speed of the ADATA S102 with the manufacturer's claims.

Let me remind you that the read speed was stated to be 34 MB/s, and write speed – 21 MB/s. CrystalDiskMark shows similar results, although reading falls a little short.

Everything in the world is relative, so I pitted the ADATA's speed against the Transcend, which felt a little slower than its recently missing sister.

With read speeds comparable to ADATA, Transcend was a third slower for sequential writes, but 2.5 times faster for 512K random writes. By the way, Transcend claimed a read speed of 31 MB/s and a write speed of 12 MB/s for this flash drive.

Sandisk, who faithfully serves his brother, showed himself like this (we will do without a screenshot):

Sequential read: 25.969 MB/s | Sequential write: 12.985 MB/s
Random read 512KB: 25.654 MB/s | Random write 512KB: 1.946 MB/s

By the way, his results confirmed that a random recording is not the most strong point ADATA flash drives.

USB 3.0 speed test

Since the ADATA S102 was the only flash drive with a 3.0 interface, it competed with itself and won unconditionally :)

When connected to a USB 3.0 port, the sequential read speed increased by more than 3 times, which is almost 2 times faster than the 68 MB/s stated by the manufacturer.

Sequential recording became 1.5 times faster than when connected to port 2.0, also exceeding the performance stated by the manufacturer. Interestingly, random recording became even a little slower.

Results

Let's sum up the intermediate results:

• The USB 3.0 interface is coming – in a few years it will dominate the market;
• real speed devices depend on themselves, as well as the USB controller in the computer and the driver installed on the system;
• Not all yoghurts are equally healthy, i.e. flash drive speeds can vary greatly;
• flash drive manufacturers indicate on their websites adequate reading and writing speed estimates;
• Based on the tests, USB 3.0 devices are clearly faster (in my case, reading was 2-3 times faster, writing was 1.5 times faster).

CrystalDiskMark tests give dry numbers, but it’s not very clear what this translates into in real life. In a couple of days I will bring to your attention a comparison of flash drives and USB interfaces for typical operations with files and folders.

USB 3.0 | Where does the speed go?

Every day we enjoy the ease of use and instant connection of USB devices. But sometimes we just curse the interface. USB with plug and play technology is incredibly convenient. But sometimes, as if out of spite, it refuses to detect the device or provide the speed of working with it that we expected.

USB 2.0: looks like it will last all day...

With the advent Intel chipsets seventh series and AMD Fusion Controller Hub supporting USB 3.0, it is difficult to imagine how we could use the first generation of the USB interface more than ten years ago. The maximum throughput was 1.5 MB/s, and files were transferred terribly slowly over USB 1.1, but the situation was partially mitigated by the small capacity of USB drives.

A couple of years later, we were introduced to the updated USB 2.0 interface, which had a maximum declared transfer speed of 60 MB/s - a huge leap compared to USB 1.1. Nevertheless, new interface was limited by protocol overload and 8/10 bit encoding, as a result, the actual transfer speed of USB 2.0 was in the range of 30-40 MB/s. At that time this was enough. But with the growing popularity of affordable external RAID storage and SATA-based SSDs, we have become more sensitive to performance, and it gradually became apparent that USB speed 2.0 is starting to fall short.

USB 3.0 satisfied our need for a higher throughput interface, with a maximum of 625 MB/s. If we take into account the signal transmission factor, we get a ceiling of 500 MB/s. But even so, actual performance never seems to reach as high a level as the optimistic graphs indicate bandwidth, which motherboard suppliers like to put on the box of their products.

USB 3.0: Better. But we are waiting for more!

Based on the speed of flash drives and external hard drives, which we have in our laboratory, we were afraid that we would never achieve the stated speeds. However, we begin to study the work USB 3.0 and try to find out if there is any possibility to increase the data transfer speed over this interface.

USB 3.0 | What slows down the interface speed?

Why are our devices based on USB 3.0 running at approximately 150 MB/s when the interface's stated maximum is 500 MB/s or so? To understand the internals of USB, you need to understand basic speed and power.

Since USB is not very suitable for transmitting unmodulated data, the information must be encoded using line code and then decoded at the other end. This is an important point that allows the receiving side to restore synchronization. Without this, there will be many more transmission errors. Like many other interfaces (for example, optical Gigabit Ethernet), USB uses 8/10-bit linear redundancy encoding, which turns eight-bit data into ten-bit data, thereby achieving edge matching. Although 8/10 bit encoding provides the necessary stream synchronization, it reduces the bit rate useful information by 20%.

Therefore the data transfer rate USB 3.0 5 Gbps becomes 500 MB/s peak throughput. But this is not the only factor that eats up the real transmission speed.

In the characteristics USB 3.0 On the USB Implementers Forum (USB-IF), under paragraph 4.4.11 the following is reported:

The effectiveness of SuperSpeed ​​USB depends on several factors, including 8/10-bit character encoding, packet structure and framing, flow control, and protocol overload. At a data rate of 5 Gbps with 8/10 bit encoding, the net throughput is 500 MB/s. When flow control, packet structure, and protocol congestion are taken into account, payload throughput is 400 MB/s or more.

Suddenly speed USB 3.0 lost another 100 MB/s. However, even 400 MB/s looks pretty good compared to 40 MB/s for the USB 2.0 interface.

While these numbers help temper expectations for USB 3.0, they do not answer the question of why the actual figures are so much lower. We still ask why devices with interface USB 3.0 so slow when the specifications indicate much more bandwidth?

First, the controller of the device itself greatly affects performance. In the graph above, the Thermaltake BlacX 5G is definitely faster than the Apricorn SATA-to-USB 3.0 Adapter, but you'll only see that data using a high-end SSD. What's more impressive is that the BlacX 5G can outperform Buffalo's external RAID storage, the result of which is shown in the first graph. Of the three devices noted, only the BlacX 5G uses the ASM1051 controller. Based on our experience, devices that support USB 3.0 and using ASMedia controllers provide more high level productivity. But this advantage alone is not enough to pass the 300 MB/s barrier and move towards peak interface performance.

Secondly, the interface controller itself has a significant impact on throughput. We carried out the above tests on “native” ports USB 3.0 motherboard ASRock Z77 Extreme6. With that said, we have seen inconsistent performance numbers and the results seem to be implementation dependent. The Etron controller on one board provided 250 MB/s, and the same controller, but on a different platform, could not exceed 200 MB/s. However, in general, the loss is most associated with USB in the Platform Controller Hub or Fusion Controller Hub.

And lastly, despite the fact that the interface USB 3.0 capable of providing 400 MB/s, its potential is hampered by an inefficient protocol. All types of USB include four types of transfer: control, interrupt, isochronous transfer and linear transfer. The first two types, Monitor and Interrupt, define how the host communicates with devices. The third type, isochronous transmission, is required for periodic and continuous data transmission, it defines how a device can reserve a certain amount of bandwidth with a guaranteed latency. Isochronous transfer is commonly used in audio/video devices such as capture cards because it solves the problem of data loss (lost frames in video) when using multiple devices connected via USB. And finally, the bulk-only transport mode interests us most today, because it is used to transfer data to USB storage devices, etc.

Bulk-only transport, known in engineering circles as "BOT", was developed in 1998 for USB 1.1 as a protocol that accepted and processed one command at a time. BOT technology was specifically conceived for the needs of USB flash drives, which at that time had a small capacity and speed. Because of this, BOT is similar to an IDE in that command queuing is handled on the host (which explains why USB performance drops as queue depth increases).

"BOT" technology has remained unchanged since USB 2.0, which debuted in 2000, probably due to the fact that the speed itself USB bus is a bottleneck, and there is no point in updating the BOT. But in retrospect this may not be true because USB 3.0 no longer slower than the devices attached to it.

USB 3.0 | Turbo Mode: Faster USB, with caveats

Maximum transaction size for BOT transfers per level operating system is 64 kbytes. However, serial data is typically transferred in 128 KB blocks, which requires two BOT transactions. A technology called "Turbo mode" attempts to overcome this limitation by increasing the maximum transaction size to 1 MB or more, allowing USB driver pack several sequential 128 KB requests into one large transaction. Fewer small transactions mean fewer USB wait, prepare, and commit commands, which in turn increases throughput.

With Turbo mode, USB 2.0 speed typically increases by 8-10 MB/s, and performance increases by ~25-33%. The increase will be regardless of whether you use a regular hard drive or an SSD, because the speed of the drives is higher than the throughput of the interface.

If you have one of these Asus motherboards, then in the Asus utility USB 3.0 Boost, along with the Normal button, either a "Turbo" or "UASP" button will appear at the moment when the port is connected USB 3.0 the corresponding device is connected. And it doesn’t matter whether this port is a chipset port or is served by a separate controller. Turbo mode is typical for any USB 2.0 or USB 3.0 without UAS, and if your device connected via USB 3.0, supports UAS, then Turbo mode will not be available to it. By default, all devices are set to "Normal" (BOT) mode.

ASRock's XFast USB software looks more polished and enables Turbo mode on any USB port, even if the drive is not yet formatted with NTFS or FAT. However, only Asus allows you to enable UAS protocol in Windows 7 using a licensed driver MCCI ExpressDisk UASP Driver .

The Asus UASP driver performs better than the BOT and native UAS driver in Windows 8, especially with random read operations.

When transferring data serially, the UAS driver in Windows 8 is faster, delivering almost 360 MB/s, beating the Asus UASP driver by 25 MB/s in read operations. For comparison, the maximum for BOT is ~300 MB/s. Asus' UASP driver leads the way in sequential writing, reaching ~340 MB/s. UAS Driver Windows systems 8 only gives ~325 MB/s. But both UASP modes provide a noticeable improvement over BOT, which peaks at ~315 MB/s.

USB 3.0 | Enable UAS on older motherboards with USB 3.0 support

As we've already noted, even if you have a device that supports UAS, the system you install it on must also support it, otherwise it won't do any good. To do this, you need to take into account hardware and software factors.

Kit Windows drivers 7 doesn't include UAS support, here's why Asus utility USB 3.0 Boost has configuration inf files in the installation subfolder. These files are the missing link.

As it turns out, you can technically use these same drivers to enable UAS manually. However, there is one obstacle on this path. When Asus company licensed the MCCI UAS driver, it added a routine that checks the manufacturer and model of your motherboard. If you are using a board from another company, things immediately become more complicated (although we got the utility to work in our lab).

But if CPU-Z detects your motherboard manufacturer as "ASUSTek Computer INC", manual replacement"USB Mass Storage Driver" to "ASUS USB 3.0 Boost Storage Driver" in the system properties adds a second "UAS Storage Driver."

Trying to do this trick on a non-Asus board will result in an error message. The only way to get around it is to modify the SMBIOS line with special utility. Again, not everyone will want to fuss so much, especially considering that this is not the whole procedure.

To be sure, we took the old one Asus board, which has USB 3.0, but does not support UAS.

Hardware

Just because the driver is installed does not mean that UAS is working. Adequate hardware support is also required. Let's take Asus P8P67 Deluxe as an example. Of course, it contains the required SMBIOS line, but it uses a Renesas controller USB 3.0, so this model is not listed in the list of boards that support USB 3.0 Boost. All boards in this list have one common component - the ASMedia ASM1042 controller.

The fact is that the ASMedia controller supports UAS, but Renesas does not. We managed to get UAS to work through the “native” port USB 3.0 Z77 chipset using Windows 8 on motherboard ASRock Z77 Extreme6 (along with the Asus UAS driver on the P8Z77-V Deluxe board with the Z77 chipset), this suggests that the Intel onboard controller supports the UAS protocol.

In comparison, the old Renesas controller either lacks the necessary hardware support or requires a driver update.

It would probably be easier to buy a card Syba USB 3.0 PCIe (SD-PEX20112). This low-cost solution works because it is based on the ASM1042 controller, which supports the UAS protocol. Just install the ASM1042 driver from Asus and you are ready to go.

Test runs of Iometer on Thermaltake BlacX 5G connected via Syba card USB 3.0, confirm the operation of UAS. The sequential read speed reaches 325 MB/s, which is what we wanted to see on a board with native UAS support.

USB 3.0 | Towards higher productivity

Performance USB 3.0 varies greatly depending on controllers, devices and host, as evidenced by our test data. And it was really worth doing the research to figure out which combination of ingredients would give the best results.

Turbo mode and UAS are two attractive technologies that improve initial behavior USB 3.0. But both solutions require devices that will not “eat up” performance and allow the interface to develop to its full potential. Connect an external hard drive via USB 3.0, and it will run at the same speed in almost any situation. To really feel the difference, you need to use a fast SSD.

But don't expect increased random I/O performance. We can imagine how many people rely on a drive connected via USB and working with tasks that involve a large number of operations with a random location of data, and we want to point out that Turbo mode and UAS will not help you with this. In fact, only linear read/write operations will benefit from speed gains in these modes.

This may be strange, but we saw the biggest speed increase thanks to Turbo mode on devices USB 3.0, which demonstrated the lowest level of performance. The Apricorn SATA-USB 3.0 Adapter, our favorite lab tool, uses a poorly optimized controller. Many are cheap USB 3.0-storage and flash drives fall into this category, and these are the devices that benefit the most from Turbo, which is good since Turbo mode is by definition free.

However, turning on Turbo mode is of no use when you are using more expensive devices on the base USB 3.0, such as Thermaltake BlacX 5G, because their performance in standard mode (BOT) is already good enough. In this situation, UAS makes a big difference, depending on your system, the serial data transfer speed can be 20% faster.

UAS is relative new technology, so we will refrain from drawing any conclusions at this time. Some of the suppliers we contacted said they were getting better results in their labs, and we have reason to believe that. According to some engineers, with new devices being developed, the speed of sequential operations reaches 430 MB/s, and random operations - 100 MB/s. For comparison, on our equipment we managed to get 350 and 70 MB/s, respectively.

After all, the UAS interface offers enormous potential, and enthusiasts may not be the only ones to benefit from it. As one of the engineers noted Western Digital, this technology is more relevant for mobile systems and desktop environments entry level. When operating in BOT mode, USB is heavily loaded CPU, and this explains why USB 2.0 and USB 3.0 very often run slowly on older systems. The UAS protocol is more efficient and produces significantly less CPU load. The addition of command queuing support has opened the door to increased performance as operations are processed in parallel. All this ultimately helps improve performance on older and cheaper computers, freeing up the processor for other tasks.

I haven't stopped describing yet USB operation ports. This time I want to touch on the topic of USB speed. All modern laptops and desktop computers are equipped USB interfaces. You can increase the number of connected devices to several dozen using so-called hubs. There are also devices that do not care about USB speed, for example, mice and keyboards, but memory storage devices (flash drives and hard disks) are very dependent on these parameters. It happens that when transferring files to a disk connected via USB, it is very small, and this is not good.

What to do if it works slowly? USB port? If such a situation arises, I have prepared a number of reasons that describe these problems, as well as solutions that will help speed up USB. I hope this article helps you.

Reason #1 – old USB types

This means that your device has ports that belong to the old specification. Now there are three types of ports: USB 1.0, USB 2.0, USB 3.0, there are also USB version 3.1.

There are, of course, many differences between these versions, but mostly not related to appearance, but in terms of speed.

Of course, USB 3.0 is the fastest; it is also marked in blue, so it will be difficult to confuse it with other versions. I also want to remind you that if you have a device, let's say HDD, which is capable of operating at USB 3.0 speeds, but you connected it to a 2.0 port, then it will not work with maximum capabilities.

Here are a couple of parameters for each port:

USB 1.0

• Maximum speed 12 Mbit/s;
• Cable length Max 5 meters;
• Number of connected devices Max – 127;
• Supply voltage – 5 V.

USB 2.0

The standard has undergone significant changes, which you can find below.

• Maximum data transfer rate 480 Mbit/s;
• For keyboards, mice and joysticks, 1.5 Mbit/s is sufficient;
• For audio and video devices – up to 12 Mbit/s.

USB 3.0

IN this standard you can notice the increase in data transfer speeds up to 5 Gbit/s, and with the emergence of version 3.1 up to 10 Gbit/s. It also became possible to simultaneously transmit and receive data, which increased the speed of work. It has a high current strength, which helps to connect any hard drives without problems, and also to charge some devices, such as smartphones, faster. USB 3.0 is compatible with all previous standards.

What should be done? I advise you to purchase a PCI controller, but more on that below.

What ports are on your laptop or computer?

I have already written about this in more detail. But there are a couple of points that are not included in that article. Firstly, you can use the documentation for your motherboard or laptop and technical specifications find out everything.

The second point is to use special programs that show all technical and software characteristics computer.

As an example, I will give the utility AIDA64, since I often use it myself. You can download and trial version from the official website. So, let's go to the section "Devices" and there we select the item « USB devices» , on the right you will see all the ports that are built into your computer.

Reason #2 – maximum speed is disabled in the BIOS

Sometimes it happens. If you notice that the speed of that USB 2.0 is suspiciously low, then look for USB-related settings there. They can be located in the tab Advanced. There you can switch the parameter to Hi-Speed or FullSpeed. I can’t tell you exactly, because different versions BIOS parameters labeled differently.

Reason #3 – No USB ports

IN modern laptops And motherboards it's practically impossible. At least a couple of USB 2.0 ports will definitely be built-in. Of course, if your situation is completely different, then you can purchase a controller without any problems PCI USB, for example, versions 2.0 or 3.0, or all together. For the price they are not very expensive. For example, you can find a USB 3.0 controller for 700 rubles.

Installation is also quite simple. The main thing is to know what a PCI slot looks like. Before taking any action, be sure to turn off your PC and unplug it. Next, you can pull out the cover of the system unit and check the free PCI slots; if there are any, then insert our controller there. After turning on the computer, everything will already work, the necessary software will be installed automatically.

Reason #4 – operating speed at USB 1.0 level

Another problem arises. In this case, you may even see a message like this: “A USB device may work faster...”. This means that you have a free high-speed port on your PC, and you need to connect devices to it.

If you notice that USB 2.0 or 3.0 has a speed of 1.0, then the culprit may be. Maybe they need to be updated to latest versions, or delete them, and the system will install them again. This is done as follows:

1. Go to device manager - keys Win+X and selecting the appropriate item;
2. Open the tab "USB Controllers";
3. On the desired device, double-click, and then go to the tab "Driver", where we click "Delete".
4. Click on the tab "Action", and then select the item "Update hardware configuration".

There is also one caveat when copying files. The speed will be much slower if you copy many smaller files. If you want to higher speed, then collect such files into one archive.
