USB 3.0 (4.8 Gbps) provides TEN TIMES the capability of USB 2.0 (480 Mbps); it also provides up to 900 mA power instead of the 500 mA available with USB 2.0. Type A connections are backwards compatible to USB 2.0 and even USB 1.1. Finally, while USB 2.0 cables will work with USB 3.0 devices (at the lower USB 2.0 transmission speed and power), you won't enjoy the Super Speed of USB 3.0 without connecting with USB 3.0 cables!
