I've, fortunately or so it seems, never looked at a Green drive, but I
have wondered about getting a WD Red for my house server, which runs
24/7. Have you tried that colour?
Currently all my systems are on WD Blue, apart from an old Lenovo R61i,
which has a Sanyo 128GB SSD fitted. Before you ask, the R61i's disk
interface is unable to talk to a disk of more than 200GB. Its original
disk was 128GB and when that died the smallest HDD I could buy was 320GB.
I tried a 500GB disk in it: no dice, but 128GB SSDs were around and
that's what it got. Puugged in, worked immediately.
I'm pleased with that. Currently the machine is running 47/7 doing
protein 3D shape fitting. The trimmer currently reports tidying up about
2GB of blocks per week, so evidently the protein mangler uses more disk
work space than I'd imagines it would. But, the oddity is that in all my
HDD-based systems, smartd reports around 40-45 hours of spun-up time per
week for this T440 and maybe 50-60 hours per week for the for the always-
on house server, but the SSD-equipped R61i which runs the protein folding
stuff 24/7 never reports a weekly 'spun up' time of more than 1-2 hours.
My best guess is that this is due to the SSD reporting that its parked
whenever its not actually reading or writing, but that's just a guess:
what do I know about SSDs?
