Quite interesting .....
..... as I never used the low power eco WD's (always bet on black) until I threw a 2TB Red in the NAS box. The WD blacks in my main system have been hammered to hell over the years thanks to Steam but have only had an issue when they have been moved to older boxes as they were replaced. I just think WD's don't like being moved.
Extremely surprising were the Hitachi results as in the early 2000's we simply referred to them as Deadstars when they were still IBM owned. No wonder WD snapped them up.
