25GB in 70 seconds. That's the torrid transfer rate consumers can expect with devices based on the USB 3.0 specification, which debuted Monday.

Intel, Microsoft, Texas Instruments, and NEC are the leading players in the group.
Among the initial devices, external solid-state (flash) drives and hard drives are expected to be popular. "The first SuperSpeed USB devices will likely include data storage devices such as flash (solid-state drives), external hard drives, digital music players, and digitial cameras," the group said.
Products aren't coming until 2010, however. "It is anticipated that initial SuperSpeed USB discrete controllers will appear in the second half of 2009 and consumer products will appear in 2010," according to the group.
"The USB 3.0 Promoter Group is now accepting adopters of the USB 3.0 specification, which has been finalized at the 1.0 level," the group added.
As its name (SuperSpeed) implies, USB 3.0 is all about speed. About 10 times more speed, to be exact, than the 2.0 specification.

Microsoft's talk Thursday was predicated on the expected finalization of the specification later this month. On Wednesday, Jeff Ravencraft of Intel said that he expects the final specification to be announced in San Jose, Calif., on November 17. Ravencraft is also the chairman and president of the USB Implementers Forum (USB-IF) industry trade association.

(Credit: Brooke Crothers)Microsoft expressed caution about USB 3.0--which is expected to offer 10 times the performance of USB 2.0--because finalization has taken so long. "Because the current USB 3.0 spec is currently not signed off, we're challenged and we won't have support for USB 3.0 in Windows 7 at RTM (release to manufacturing)," Lars Giusti of Microsoft said in a WinHEC session here titled "USB Technology Update and Windows Strategy."
"Our goal is to have the USB 3.0 specs signed off by the promoter's group sometime later this month. Hopefully," he said.
Delays have held USB 3.0 back, Giusti said. "That makes it challenging for several reasons. Since the spec isn't signed off we don't see any USB 3.0 hardware in the market or even prototypes available yet. With those two disadvantages we cannot develop, create, and design support yet for USB 3.0. But we are staffing up. We are making plans," he said.
He continued. "If you look at the USB 3.0 industry timelines and checkpoints, it really has been a very long, difficult and challenging three-year effort."
Giusti then made some predictions about the adoption of USB 3.0. "In 2009, the signed-off spec will be handed over to the implementers and those adopters that plan to productize USB 3.0," he said. "Our prediction tells us that in 2010 finally we'll see broad-scale product deployment of host controllers, devices, and systems that are USB 3.0 and SuperSpeed capable."
Currently, Microsoft is trying to figure out which operating systems will be USB 3.0-capable. "The Microsoft USB core team is currently evaluating which operating systems we should support USB 3.0 on. It's a difficult decision and a difficult choice 'cause there's all these moving parts," he said.
"Our early indications tell us that most partners think that we should support USB 3.0 on at least Windows Vista."
