USB 3.0 is "SuperSpeed"

Recently revealed details of the future USB 3.0 standard confirm it will support up to 10x the theoretical bandwidth of today's common USB 2.0 technology. USB 3.0 will be the first version to support full duplex (simultaneous bidirectional) communication (that gives two of the 10x of improvement).

While 2.0 has also been known in the industry as Hi-Speed, USB 3.0 will be SuperSpeed. USB 3.0 requires using new cables to achieve the higher speeds, but 2.0 and 3.0 are also mutually compatible, meaning that cables of either type work with ports of either type (at lower speeds).
