SuperSpeed USB 3.0 to be Formally Unveiled Next Monday

Almost 14 months after Intel announced USB 3.0, the final protocol specification will be formally announced next Monday at the first SuperSpeed USB Developer Conference in San Jose, CA. The specs will then be handed over to early adopters that plan to design products around SuperSpeed USB 3.0. The third generation of Universal Serial Bus has been hit by delay after delay, and it's been a very long, difficult and challenging three-year effort. Only several months ago, nVidia, AMD and a few others threatened to create its own USB 3.0 if Intel doesn't share the controller specs with them on time. This fortunately didn't sidetrack the effort to deliver USB 3.0 on time as both sides quickly reached an agreement.

While not formally unveiled, the SuperSpeed USB logo was shown at WinHEC 2008 last week where Redmond engineers held discussions on which OS will support the new USB. Windows 7 RTM unfortunately won't ship with native USB 3.0 support; that is, if the next Windows doesn't encounter delays. Hopefully, USB 3.0 (with its new SuperSpeed USB mode) is worth the wait with speed boost to 4.8Gbps, the use of optical cabling, and new power management. WinHEC 2008 has a a brief performance comparison sample for data transfer of 25GB HD movie:

• USB 1.0: 9.3 hours
• USB 2.0: 13.9 minutes
• USB 3.0: 70 seconds
