The USB 3.0 Promoter Group on Wednesday announced the completion of the USB 3.1 specification which adds enhancements to enable SuperSpeed USB to operate at up to 10Gb/s. This latest release of the specification will be available today for download from the USB implementers forum (USB-IF) website.

“The USB 3.1 specification primarily extends existing USB 3.0 protocol and hub operation for speed scaling along with defining the next higher physical layer speed as 10Gb/s. The specification team worked hard to make sure that the changes made to support higher speeds were limited and remained consistent with existing USB 3.0 architecture to ease product development,” said Brad Saunders, USB 3.0 promoter group chairman.  

SuperSpeed USB 10Gb/s uses a more efficient data encoding and will deliver more than twice the effective data through-put performance of existing SuperSpeed USB over enhanced, fully backward compatible USB connectors and cables. Compatibility is assured with existing USB 3.0 software stacks and device class protocols as well as with existing 5Gb/s hubs and devices and USB 2.0 products.

“The industry has affirmed the strong demand for higher through-put, for user-connected peripherals and docks, by coming together to produce a quality SuperSpeed USB 10Gb/s specification. Intel is fully committed to deliver on this request,” said Alex Peleg, vice president of Intel architecture group.

Developers interested in implementing the new USB 3.1 specification have the opportunity to learn technical details during three developer conferences currently being planned.

“In this multi-device world, the USB 3.1 updates will enable end-users to move content across devices quickly, conveniently and without worrying about compatibility. AMD thanks our engineers as well as the other technology contributors for bringing to market robust innovation that is designed to work seamlessly with new and existing solutions,” said Emile Ianni, corporate vice president of platform solutions engineering at AMD.

Companies like Hewlett-Packard as well as Texas Instruments also announced endorsement of the USB 3.1.

USB has nothing to do with Thunderbolt.

Looking very much forward to this as then USB3.1 can help saturate the fastest SSDs (600mb/sec read/write) AND are backward-compatible, AND have ubiquitous connectivity (unlike Thunderbolt which is no where close to numerous), and other features (full multi-monitor, more power to devices).. WinWin to consumers for sure.

Again, you cannot compare Thunderbolt with USB, two different connections with two different goals.

I look for overall connectivity options and availability of devices to which USB3 wins hands down. I use off-line storage via USB3 and its insanely far better than USB2 and TB isn't remotely a consideration due to cost and availability of devices. It can MAKE ME BREAKFAST in the morning all it could but if I cannot get to it and cheaply then FCUK KINDLY OFF! USB3 is everywhere and back and does the trick quite well for most of us. TB is currently not many places, costly, and over-rated. Someday I'll move to it for mass offline storage but not even close right now.

USB 3.1 will compete with Thunderbolt based on the factors mentioned above- raw speed, cost, and ubiquity. And will probably "win" the way that USB 2 "won" over FireWire. Even though USB 2 and FireWire are different connections with different goals...

again USB boyz are barking .........they said in past USB 2.0 will hit 400mb/sec. and what we got read speed not more than 40mb/sec.,write speed from 1mb/sec to 25mb/sec(depending on file).
shut up u barkers just tell what speed we will get in our thumb drives.

Are the "USB boyz" you're taking about the manufacturers\USB consortium or are you referring to users?

Yea USB is kinda a fugly ugly standard, but at least it's "open" these days - and I'll stop that rant there.

But I do agree that it was rather lame back in the day with USB 2 where everyone quoted "maximum throughput speed theoretically obtainable with a perfectly spherical cow" and neglecting things like... basic required protocol overhead.

Kinda like how 3.5in HD floppy disks were marketed as 2MB... before you format it. Like gee let me know how attempting to use an unformatted disk is useful for doing exotic tasks like... storing data. *sigh*
