USB 3.0 Cable

USB 3.0 Cable

USB 3.0 spec has been released! Varying reports, but it looks like USB 3.0 will have 10x higher data rates (4.8Gb/s vs 480Mb/s), higher current (900mA vs 500mA), and a new interrupt driven protocol. You may notice that they have changed the female plug which means I wouldn’t hold my breath when it comes to backwards compatibility. Luckily, we’ve got until 2010.
