So far we have followed two versions of this interface between the PC and device: the USB 1.0 and 2.0. It 's time to pick up a new version, USB 3.0, offering important advantages over previous ones. It should first be clarified that are backward compatible, ie older versions will not be thrown away but can still be used, since the 3.0 will recognize.
Great improvement is definitely the speed of transfer is referred to as 5 gigabits per second, 10 times that of USB 2.0. To better understand these numbers should give you an example: to transfer 25 gigabytes of data, a magnitude, it takes only 70 seconds, just over a minute! Also, we will also call Superspeed USB ports.
Another major improvement is the optimization mode and energy saving, very useful in times like these where the cost of energy continues to increase and we are all more sensitive to the environment. Finally details on compatibility: there are no preferences on the new operating systems, both Linux and Windows XP, Vista and Windows 7 (later).
