USB 3.0 Performance to Double with New Capabilities

The USB 3.0 Promoter Group today announced development of a SuperSpeed USB (USB 3.0) enhancement that will add a much higher data rate, delivering up to twice the data through-put performance of existing SuperSpeed USB over enhanced, fully backward compatible USB connectors and cables. This supplement to the USB 3.0 specification is anticipated to be completed by the middle of this year.

Key characteristics of the higher-rate SuperSpeed USB solution include:
● New 10 Gbps USB data rate
● Compatibility with existing cables and connectors
● Improved data encoding for more efficient data transfer leading to higher through-put and improved I/O power efficiency
● Compatible with existing USB 3.0 software stacks and device class protocols
● Compatible with both existing 5 Gbps and new 10 Gbps USB 3.0 hubs and devices, as well as USB 2.0 products

"With USB technology continuing to be the data and power delivery path of choice across personal computing and consumer electronics, we are always looking ahead to how to best improve user experience and connectivity performance," said Brad Saunders, USB 3.0 Promoter Group Chairman. "Doubling SuperSpeed USB performance will be especially beneficial for emerging USB docking and storage applications."

"For our customers, 10 Gbps USB represents an important evolution in this ubiquitous I/O standard," said Mark VandenBrink, Vice President and Chief Technology Officer, PC Global Business Unit, HP. "By doubling the bandwidth while maintaining full backwards compatibility with the broad ecosystem of USB peripherals and software, we will be able to better meet the needs of our customers with this high-speed technology."

"We recognize that more mainstream client computing applications are going to need higher through-put to user-connected peripherals and devices," said Alex Peleg, Vice President, Intel Architecture Group. "Intel is fully committed to delivering 10 Gbps USB performance to these platforms while retaining compatibility with the existing USB ecosystem to help to satisfy user demand for low-cost, higher-performance solutions."

"Microsoft has been a strong supporter of the USB community where we have advocated balancing innovation and compatibility. The planned updates to USB 3.0 are consistent with our views," said Dennis Flanagan, General Manager, Windows Ecosystem Engagement. "These updates will enable higher data rates and allow combining of disk, high-definition audio/video and networking traffic on a single cable — all while maintaining compatibility with billions of existing devices."

"This enhancement builds on the tremendous success of USB and expands its capability by doubling the data rate," said Roland Sperlich, TI Consumer and Computing Interface Product Line Manager. "While maintaining backward compatibility, the 10 Gbps data rate allows users to do more with a universal standard that can be leveraged by many industries."

The 10 Gbps SuperSpeed USB update is targeted for industry review during the first quarter of this year. Further information regarding the specification and plans for pre-release industry reviews will be provided via the USB Implementers Forum (USB-IF) website at http://www.usb.org/developers/USB-Futures.pdf.

ack, they're splitting it up and changing speeds without changing the name of the device?


this will only lead to mass confusion

It's the same thing, it's USB3.0 but with updated specifications. Just like HDMI v1.0, 1.2, 1.3, 1.4 etc. If they released another cable that was not compatible, the media would have eaten them for lunch.

Anyhow, great move. This is killing SATA and going against Intel's ThunderBolt.

it is and it isnt.

hardware compatibility is great - but CHANGE THE NAME.


otherwise, theres going to be devices out there that are impossible to tell the speed difference. look at the average consumer and wifi N, with its various speeds and technicalities (150, 300/150, 300, 300+300 on 2.4 and 5GHz to make N600...)


if its twice as fast, call it something else!

It will probably be called USB 3.1 in technical specifications but still keep the "SuperSpeed USB" moniker.

Just in Theory. ATM even with helps like USB-Turbo mode (Asrock) or UASP USB3.0 gets just over 300MB/s at best, without these its mor like 250-270MB/s. So best we can expect from USB3.0 2.0/b/superduperhyperspeed is about the same performance as eSATA 6Gb/s - but until this hits the market, there will be SATA Express with 8-16GB/s.

Will just be like PCI-E specs so USB 3.0 x 3 and so on.
