My box is not on 24/7, it turns on for a news recording at 6pm and most of
our TV watching happens in the evenings, so normally <6 hours per day. The
two Toshiba 1TB drives that I have been using show 14 months of spin time
over some 5 years of service. I'm currently awaiting the arrival of a new
Kingston SSD for my OS (previous drive died due to overheating, not enough
air moving in the cabinet the box hides in, add fan voila) It appears that
the Barracuda drive is similar to, if not a re-brand of my original
toshibas, but I'm curious about the WD purple drives hyped as for CCTV.
Does anyone have experience with them? Is recording and deleting TV enough
like surveillance to justify the extra initial expense?
