Universal Serial Bus3.0 explained

USB3.0 is a data bus using new mode called SuperSpeed and it’s able to handle an operation at 5Gbps. Initially USB technology provided 3 speeds (1.5Mb/s, 12Mb/s and 480Mb/s) that peripherals could use. As PCs become increasingly powerful and able to process larger amounts of data, users needed to get more data into and out of their PCs. USB is a successful way to connect printers, mice, portable players...

The objective of the USB3.0 is to provide more bus bandwidth because users nowadays download large amount of data. Devices such HD camcorders ask for ten of gigabytes of storage that the user will want to move to their PC for editing, viewing and archiving.

USB3.0 is a great solution for wireless devices and mobile architectures. USB3.0 is intended as an enhancement to PC architecture, Spanning portable, business desktop and home environments, as well as simple device-to-device communications.

Normally, all USB3.0 devices must provide support for both USB3.0 SuperSpeed and USB2.0 High-Speed, however, if the USB3.0 device is connected to SuperSpeed compliant port it will operated at 5Gbps instead of 480Mbps.
