At first I was very impressed by the drive, very quickly, silently and energy efficient. The plate was used as a system disk and has done a good job. Today, however, after about 3.5 months of Gau:. Disk is detected on any controller more and is actually completely dead Now I'm going to see how the Amazon customer service so that moves, because the guarantee is not to yes. Should they be replaced, I will however no longer be used as a system disk, that's me too hot. Too Bad.
