The drive sizes are simply the physical size. Operating systems don't make a difference either. The question you raise about "the best drive to buy" is a subjective one. Western Digital has been mention quite a lot. All I would say is that I have had Western Digital and not had any problems with it. Hope this isn't too vague. Regards.
