Unless you are on the bleeding edge of technology, chances are you haven’t used a USB 3.0 device yet. And unless you’re constantly reading up on the latest and greatest technology, you might not even know what USB 3.0 is all about.As the name implies, USB 3.0 is the successor to the ubiquitous UBS 2.0 interface. It provides faster transfer rates -- up to 5.0Gbps using a technology dubbed SuperSpeed. This is more than ten times the speed of USB 2.0 and, while you won’t get speeds like that in real-life use, you will see significant improvements over USB 2.0. It is also significantly faster than eSATA, FireWire-800, and FireWire-400.
