What is the difference between USB 2.0 and USB 3.0 ?

What is USB 2.0 ?

USB 1.0 was the original specification for flash drives, followed by USB 1.1, which was a bit faster (circa September 1998). USB 2.0 is a newer (since 2001) and faster specification, 40 times faster than USB 1.1 and the current de-facto standard for most peripheral devices (cameras, scanners, hard drives, and flash drives). USB 2.0 chips transfer data at an average rate of 40 to 60MB/second.

What is USB 3.0 ?

Since January 2010, even newer technology was released to the public in the form of USB 3.0. The function is the same as its predecessors, only the hardware has been nicely upgraded to nearly 10 times the transfer rate of the USB 2.0 at an average rate of 400MB/second (0.4GB/sec). The technology is still new, so many manufacturers are coming out with these devices that are comparable to the rates of a Blu-ray DVD. USB Canada launched the USB III model in late 2010
