USB 3.0 is a major revamp of well-known and widely used Universal Serial Bus that was created in 1996. It seems that the speed we already got is never enough. Several hundred of megabits were enough only for some time, now it seems not that much. USB 3.0 promises higher transfer rates (up to 4.8 Gbps), increased maximum bus power, new power management features, new connectors and cables for higher speed data transfer (they are backwards compatible with USB 2.0 devices and computers though).

Usually it may seem that USB 2.0 is quite enough, but with ever increasing demands because of terrabyte storage devices, high megapixel count digital cameras, multi-gigabyte mobile devices 480 Mbps becomes not enough, while practically data transfer speed is about 320 Mbps. So the fact that USB 3.0 makes it about 10 times faster sounds incredible.
