USB 3.0 standard
In September 2007, exactly at the Intel Developer Forum was made the first public demonstration of this new standard, evolution of the previous USB 2.0. The new USB 3.0 standard is able to provide a theoretical data transfer rates ten times faster than the USB 2.0, reaching well 5 Gbit/s.
Consider that the former 2.0 standard was stood to 480 Mbit/s, while the first version 1.0 ensured a bandwidth of data transfer rates of only 1.5 Mbit/s, data that currently there seem pure prehistory.The new standard not only allows us to overcome the limitations of previous version of USB, the 2.0, but it also allows to overcome other competing standards such as FireWire and eSATA connections.
To make possible a so high transfer rate, the USB 3.0 has been re-designed internally, while maintaining backward compatibility with previous standards. This means that all devices that work with 2.0 interface, will continue to work with USB 3.0 port. The third generation of USB 3.0, in fact, can operate in 4 different modes including three inherited from the USB 2.0: LowSpeed 1.5 Mbit/s, FullSpeed 12 Mbit/s, HighSpeed 480 Mbit/s SuperSpeed 5 Gbit/s.
