I had an older Compaq laptop circa 2004 that had USB 1.0 and I remember trying to add over 100 songs to my iPod through iTunes. It would takeforever. I would rather wait to get home from wherever I was to transfer songs because my PC at home had USB 2.0 and the difference in speed was incredible. Now I'm sometimes transferring 10+ gigs of information from a hard drive to an external hard drive, external to a flash drive, etc. Even though USB 2.0 is fast, I still have to wait several minutes for the transfer to complete. I know, several minutes... We are so spoiled. USB 3.0 is said to be 10 times faster than 2.0 while using a third of the power and it's backward compatible. A new major feature is the SuperSpeed bus, which provides a fourth transfer mode at 4.8 Gbit/s. The raw throughput is 4 Gbit/s, and the specification considers it reasonable to achieve 3.2 Gbit/s (0.4 GByte/s or 400 MByte/s) or more after protocol overhead [1]. If you were lucky enough to go to this year's CES you probably heard about hard drives, motherboards, adapter cards, laptops and devices that are now using 3.0 technology. Expect to see a lot more about on USB 3.0 as more and more devices that support it hit the market this year.
