1 January 2013, Comments: 40

There are currently three speed modes defined by the latest USB 3.0 specification. They are SuperSpeedHi-Speed and Full-Speed.

The new SuperSpeed mode has a transfer rate of 4.8Gbps. While the specification retains Hi-Speed and Full-Speed USB mode, commonly known as USB 2.0 and 1.1 respectively, the slower modes still operate at 480Mbps and 12Mbps respectively and are kept to maintain backward compatibility. Check out the comparison between USB 3.0 and other competing interfaces such as eSATA, FireWire 800 and Thunderbolt.
