I wanted to change my external DVD burner and I came across this one. Blu-Ray ... and I jumped at the chance. I also saw the opportunity to be prepared for the future with USB 3.0. Unable to enjoy the moment because my PC is not equipped, I use e-Sata connection, also very fast. Nevertheless USB 3 is backward compatible with current USB 2 and you can use it without problems today. Really a great product and, moreover, provided with an interesting software suite that allows among others to test any kind of disk in a more efficient manner than Nero for example.
