USB 3.1: Faster, more convenient and soon for you

With the slow support of the market in the E- 3.0, which only recently showed real signs of life, we are looking at the new 3.1 standard that is expected to bring with it a number of upgrades that every user will be happy to receive

After we've looked at The special capabilities of the USB 3.1 standard Which will appear officially in the coming months, tests New ones show us the real numbers behind the new technology. First, let us recall the basic capabilities of the standard The new.

The new 3.1 USB standard was first introduced in January of 2013. Compared with the 3.0 (or USB 3.1 1) version of the USB device, which was able to reach speeds of only 5 gigabits per second, 3.1 (or 3.1 2) reaches twice the speed of about 10 gigabits per second. This speed, which is a significant improvement over previous generations of the outdated USB device, is now comparable to the speed of Intel's first Thunderbolt standard (which is also about 10 gigabits per second), with speeds of 20 Gbps per second The current Thunderbolt 2, with a third version expected to appear this year (as part of the "Skylake Of the company) will show improved speed of 40 gigabits per second.

So you're probably asking yourself what the real (as opposed to descriptive) performance of this standard is? The site AnandTech, In collaboration with MSI and ASMedia, 3.1 test against its previous versions (USB 3.0 and - 2.0), with results that we think will make you very happy.

Since the 3.1 USB device is still not commercially available in the market, an ASMedia test board is used with the ASM1352R controller attached to two drives RAID-0 array.


As you can see, even when tested USB standard 3.1 not with a controller of its own (PLCs, which usually yield better results than PLCs from other companies), can be seen as a significant improvement, 3.0 and of course the 2.0 version of the outdated device today. For example, in the reading speed test (right) 3.1 stands at approximately 703 MB per second compared to 425 MB and 43 MB per second for 3.0 and 2.0 versions of the X- Respectively. In another test 1.52 was transferred gigabytes of information (the rule as 2,860 files) 3.1 took just over five seconds to finish, 3.0 finished after nearly seven seconds and the X- The old 2.0 is finished after only about 45 seconds.

As part of the upgrades to bring the USB standard to the 21 century, the physical connection of the device, called "Type C" is a reversible connection (similar to the Thunderbolt standard) that comes with support for previous versions of the USB standard. In addition, the upgrade of the new standard (up to 3.0 amperes), in addition to the speed at which information can be transmitted (ten gigabits per second), an array in which a mobile device is also loaded by a computer to which it is connected, Displaying media onto a screen is possible, which may also place the 3.1 USB standard in the center Our Digital Life.

With the hope that Intel will not be delayed in its official support for the USB 3.1 standard in its next chipsets (as was done with the USB 3.0 standard in light of the company's attempt to promote the " ), We look forward to seeing the new device already this year in products on the market, with much broader support in the first quarter of 2016. Excited? Tell us in comments!

  1. URL = ""] Link [/ URL]) The "speed" of USB 3.1 is indeed 10Gbit / s and the encoding of the information is different to the 128 / 132 standard, ie only 3% The transmitted bits are considered overhead, which should give a working bandwidth of up to about 9.7Gbit / s or 1.2GB / s (the same link states that preliminary tests show that the overhead is closer to 30% than 3%, giving a practical bandwidth of 7.2Gbit / s or 900MB / s).

    Anyway, until the next generation of kits is not released
    It is worth noting that the "speed" (more precisely - the bandwidth) specified here is the number of bits (bits) per second, with the information being transmitted in a coded manner and thus the actual "speed" is smaller. For clarity - the USB 3.0 standard works at 5Gbit / s "speed", but the information encoded in the 8 / 10 standard, i.e. 20% of the transmitted bits is considered overhead, so the actual (actual) bandwidth of USB 3.0 is 4Gbit / s Or at most 500MB / s. According to Wikipedia (


    ) The "speed" of USB 3.1 is indeed 10Gbit / s and the encoding of the information is different to the 128 / 132 standard, i.e. only about 3% of the transmitted bits are considered overhead, which should give a practical bandwidth of about 9.7Gbit / s or 1.2GB / s ( In the same link it is noted that preliminary tests show that the overhead is closer to 30% than 3%, which gives a practical bandwidth of 7.2Gbit / s or 900MB / s).

    In any case, until the next generation of chipsets that offer natural support for USB 3.1 is released, it is impossible to know what the real performance will be. Of course, motherboard / computer support will not really help if devices with USB 3.1 controller are not released.

  2. The new connection is simply pathetic, like the users it was designed for

    Make it reversible to save a second look at the connection to figure out which side to put it in, or break a head for users who can not even do it. Stunning

    But it is smaller, thinner, and the thin plastic on which the contacts are located in the empty mid-space of the host. That is, using it (connections, disconnections, side pull, carrying USB devices away from home) will make it much easier to break the connection. And because it is soldered to the board (of computers, which today are increasingly mobile), it is not easily replaceable. But of course the users who get excited about the new connection are the ones who will have a lot of money to spend on replaceable hardware every time it breaks

    The contact resistance of the connection is the main cause of the problems in transmitting the current through it (when an external hard disk is connected to a computer, if a high quality USB cable, and it plays clicks instead of working, if there is no material problem). This is whether a stream of 0.5A on the relatively large contacts of USB2 or USB3.0. We'll see what temperatures can reach the small 3.1 connection in the 3A stream when the contacts are a little dirty as a result of the real world rather than laboratory conditions. Quest is a fun draw for everyone - of the cables that have been melted and stuck in the computer's port

  3. It is very good that you switch to reversible connections.
    I see no reason to object to the idea.

    If previous USB connections were reversible, users would be saved a lot of time and nerves.
    Hundreds of millions of times people reached behind the computer trying to connect a USB device without seeing.

  4. No problem being reversible, but hey, being mechanically and electrically resistant, not like this Apple connection ……

    And there is also no problem connecting USB cables behind the computer - try once and twice. Anyone who wants to remember that the USB icon on the plug (which can be felt to be featured) goes "up" (to you if you open the case and look at the board)

  5. Quote from the article.
    Significant and even more impressive improvement can be seen compared to the USB standard 3.0
    very impressive?
    15% is the most impressive?
    If you were writing a marginal and disappointing improvement it would be more true.
    Where is the proportionality in the description?

  6. He could try to connect the cable another 5 times in different directions while it took him to send this tweeter
