New hardware allows tenfold performance boost
V3.co.uk, 23 Sep 2009
USB 3.0 products are starting to hit the market, according to the USB Implementors Forum (USB-IF) .
The new USB format, dubbed SuperSpeed, transfers data at about 250MB/s, compared to 20-30MB/s with USB 2.0. It also has the advantage of consuming less power.
“It's 10 times the speed for less power,” USB-IF chair Jeff Ravencraft told V3.co.uk.
“Manufacturers are lining up to build it in as soon as possible.”
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.
