Summary: I used this drive on a daily basis to store video files and had no problems whatsoever. I really liked how quickly it started up, and how it could automatically turn itself on when it was about to be used. A great drive all around.
Summary: I was a bit aprehensive about the longevity of the WD Mybook after reading reviews but no problems have surfaced in 2 plus years of 24/7 use as a backup storage device. It has functioned flawlessly. I also purchased a WD backup drive for my wife's computer and it came with automatic backup software that mine lacked, however, it's a simple matter to manually backup the files I deem important and not back up less important files. I actually prefer that method.
