USB 3.0 SuperSpeed

The new USB format, dubbed SuperSpeed, transfers data at about 250MB/s, compared to 20-30MB/s with ye old USB 2.0. It also has the advantage of consuming less power perfect for mobile devices.

The new system requires a new USB host controller and a special cable but sticks with the familiar USB interface. The cable has nine interior wires, not the usual five, with two extra upload and download channels, and an extra ground wire.

NEC has already announced production of the first host controller and half a dozen other companies including Fujitsu were demonstrating applications for the new standard at the Intel Developer Forum.
