The new “SuperSpeed” USB spec will provide a 10X boost in transfer rate (from 480-Mbits/s in USB 2.0 to 4.8 Gbits/s in USB 3.0), while dramatically lowering power consumption, with broad deployment by 2010.

One example of their speed goals is to transfer a 27GB HD movie to a portable device in 70 seconds. The same thing would take 15 minutes or more with HighSpeed USB (2.0).
