What is USB 3.0? How do I know whether my computer supports it?

USB 3.0 denotes a better user experience in terms of transfer of data using USB devices. Wikipedia says: "USB 3.0 is the third major version of the Universal Serial Bus (USB) standard for computer connectivity. Among other improvements, USB 3.0 adds a new transfer mode called "SuperSpeed" (SS), capable of transferring data at up to 5 Gbit/s (625 MB/s), which is more than ten times as fast as the 480 Mbit/s (60 MB/s) high speed of USB 2.0."

So when you buy a new computer, make sure that it has at least one USB 3.0 port.

If you want to know whether a computer you're using supports USB 3.0, look for any USB port that is colored blue.
