For a single drive by itself it hardly matters anymore what you buy. You cannot predict the failure. However if you buy multiple identical drives at the same time then most likely you will either get all good drives or (possibly) a bunch of drives that suffer from similar defects and all start failing at the same point in their life cycle. For RAID arrays it's measurably best to buy drives that come from different manufacturing lots, better from different factories, and maybe even from different companies. Then, if a drive fails, assuming the failure is really the fault of the drive and not some local issue like power sources or ESD events, etc., it's less likely other drives in the box will fail at the same time.
