USB 3.0 (SuperSpeed) is a USB specification that can transmit data at up to 5 Gbit/s.

USB 3.0 is the most recent USB specification, completed in 2008. It can transmit data at up to 5 Gbit/s. USB 3.0 also introduced a new connector with 5 pins in addition to the previous standard of 4, bringing the total pins up to 9; but it still remains backward compatible with older USB devices. Most USB 3.0 ports and plugs have a Pantone 300C blue plastic insert to help users to distinguish between older USB 2.0 ports and USB 3.0 ports.
