USB 3.0 Finally Arrives

The beauty of USB 3.0 is its backward compatibility with USB 2.0; you need a new cable and new host adapter (or, one motherboard that supports USB 3.0) to achieve USB 3.0, but you can still use the device on a USB 2.0 port and achieve typical USB 2.0 performance. In reducing some overhead requirements of USB (now, the interface only transmits data to the link and device that need it, so devices can go into low power state when not needed), the new incarnation now uses one-third the power of USB 2.0.

Improvement offered by USB 3.0 is dramatic --  10X speed over existing USB 2.0 hardware. Data transfer rate of USB 2.0 was aroundl 480Mbps theoretically , while USB 3.0 can theoretically handle up to 5Gbps.(the capacity of the drive is not considered here..).
