I've had one of these for a week, and am very satisfied with the product. It has amazed everyone who has seen the drive in action, seeing the needles and platters through the window, and by how quick the OS and programs load. Ofcourse there is no point owning this drive if you aren't able to see the drive, I have a clear case so that is why I decided to spend a bit more money.
I haven't let the lower unconfirmed MTBF bother me either. By inspection of my drive it is a product of high quality, and I don't see much could go wrong with it, but if anything does happen I'll let you guys know.
