USB 3.1 specifications finalized (10Gbps speed)

Posted by David Bernstein

If you are a computer user then there is a close to 100% chance you have used a USB port for something such as a flash drive, external hard drive, printer, mouse etc. For many USB devices speed is not important and it doesn’t matter if you are using a USB 1.0 port or the latest USB 3.1 port. But for devices such as hard drive and cameras having a fast bus speed makes all the difference in the world.

USB 3.0 (5Gbps) has been out for some time and many people still don’t have USB 3.0 ports on their computer. It seems as though USB 2.0 (480Mbps) has been all the rage for the past several years. The powers that be have been working on the new USB 3.1 standard for a while and now the specifications have been released and they are looking pretty good… actually twice as good as USB 3.0.

Dubbed “SuperSpeed+” USB the new USB 3.1 will offer 10Gbps speeds and be fully backwards compatible with older versions and devices. This new speed standard puts USB in contention with Thunderbolt ports which already offer 10Gbps speeds with 20Gbps on its way. Don’t expect to see this in new computers any time soon since it takes some time for manufacturers to roll it out and of course you will have to have a USB 3.1 compatible device to take full advantage of the speed.
