USB 3.0 Getting a Speed Boost To 10 Gbps

Posted by samzenpus on from the greased-lightning dept.

cylonlover writes "The USB 3.0 Promoter Group has used CES 2013 to announce an enhancement to the USB 3.0 (aka SuperSpeed USB) standard that will see the throughput performance of USB 3.0 double from 5 Gbps to 10 Gbps. The speed boost will come courtesy of enhanced USB connectors and cables that are fully backward compatible with existing USB 3.0 and USB 2.0 devices. The 10 Gbps SuperSpeed USB update (pdf) is up for industry review during the first quarter of 2013, with completion of the standard expected by the middle of the year."

    So what's the point of having a version number on your standard, if you don't increment the number when you change the standard?

    Customer: "This computer has USB 3, but my 10Gbps device only connects at 5Gbps!"
    Support Tech: "Oh, that's because you have USB SuperSpeed 3.0 Revision 1 rather than USB SuperSpeed 3.0 Revision 2."

    Maybe call it USB SuperSpeed 3.1?

      It is a trademark of USB. Not one USB standard has had a single speed nor has it had its speed easily recognizable from the marketing garbage spilled by the consortium. And I'm not even talking about the mess of mixing USB1 & 2 devices and hubs. USB Full Speed, Hi Speed, Low Speed... and now SuperSpeed.

      To illustrate, here is an excerpt of the Wikipedia page:

      High-speed USB 2.0 hubs contain devices called transaction translators that convert between high-speed USB 2.0 buses and full and low speed buses. When a high-speed USB 2.0 hub is plugged into a high-speed USB host or hub, it will operate in high-speed mode. The USB hub will then either use one transaction translator per hub to create a full/low-speed bus that is routed to all full and low speed devices on the hub, or will use one transaction translator per port to create an isolated full/low-speed bus per port on the hub.

      Garbage.

      They obviously HAD to do the same for USB3, for old times' sake. We will laugh about it to our grandchildren next to the fireplace. But that'll be later.

      USB will never replace SATA:
        * It hits the CPU for each transfer
        * the overhead is higher
        * The latency is way higher, as it needs to set up and tear down connections for each transfer
        * It doesnt support ATA commands (TRIM, for one)

      Maybe call it USB SuperSpeed 3.1?

      It will never take off then. Everyone will wait for USB 3.11 For Workgroups.
