Great drive, but I think amazon are going through a bad batch right now.
Have had to return 2 in a row now, they work fine until about 30 hours on-time, where they start to develop problems reading, which causes everything to freeze up for a second. Noticed it first in games, but it got worse after a few days, stuttering every few seconds even in windows, eventually causing windows to hang. They also would completely stop working if you stressed them out for an hour or 2 to backup or restore content. The second one is a lot better, but it definitely the same issue, just not as bad - so far.
Not sure if I'll risk buying a 3rd from here.
