Two questions I am thinking of buying this to replace my gazillion 1TB and 2TB drives my question is... Is this a smart move how reliable are these things since my business brain is telling me just like the lightbulb, harddrives cannot be made to last otherwise the company will be out of business since why would you one sell one drive per customer's lifestime when you can sell 20.
Second question, in my search for hardrives I see they all have this "Best-Fit Applications" business and my question is how serious is that really what is fundamentally different between these disk? I use my current harddrives for such a wide variety of stuff it would be near impossible to get a different drive for each use application/case/scenario.
