The first time that I use a USB 3 hard drive, have both in PC and laptop in a USB 3 controller. With HD Tune software tested the speed, and this shows the disk is indeed a speed umd the 100MB / s. In real operation, however, the speed varies between 40 and 80, why, I do not know. Overall, however, much faster than my other hard drives with USB 2, and the system image for Windows 7 is felt triple-speed mastered. Pretty small, need no extra power, overall very satisfied - if a new hard drive, then only those. Good cable way, is doing well.
