My hard drive may be failing, looking into getting a new one. I saw this question was asked before, however it was over 10 years (!) ago: http://www.gossamer-threads.com/lists/mythtv/users/163754 The advice and thinking may have changed since then. I can get a 5TB 7200 RPM drive or a 6TB 5400 RPM ("NAS") hard drive for about the same price. Thoughts?
