The USB Promoter Group have finally provided the finalized spec for the "SuperSpeed" USB. It is said to be 10x as fast, I'm assuming that means around 4.8Gbps (Gigabites per second). Actually transfer speeds will probably be substantially less.


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 as been finalized at the 1.0 level," the group added.

USB 3.0 is backwards compatible with the older specifications. It will be a smooth transition just as the original USB to USB 2.0 has been.
