Bought a few new HDDs, because well:

This thing is obviously not reliable. Despite showing no other signs of failure. Not sure what I want to do with it. It would be a shame to throw away a working drive but I can't think of anything I want to rely on it for.
In addition my WD20SPZX failed me (entirely, it just died). I've had two WD20SPZX drives fail both within a year (one was a warranty replacement), so I'm not exactly going to trust the new warranty replacement to survive much use either. That one I'll just store some static backup files on.
I ordered a WD My Passport 4TB to replace the WD20SPZX. I'm guessing it's just a two platter variant of the unreliable WDS20SPZX, but it's got a three year warranty so I can use if for moving stuff around. Options for 2.5" HDDs seem terrible, there's three manufacturers, but Toshiba/WD doesn't want to sell SATA variants and Seagate reliability is from my experience even worse than WD.
I ordered a WD40EZRZ to replace the failing desktop drive. Might reduce noise some too to replace a black with a blue (which is actually a rebranded green) and I don't need speed anyway.
I also bought a WD40EZRZ last week. It seems to be working well though I admit I'm too lazy to do a extended s.m.a.r.t test for new drives even though I know I should. At least I have... 2 years to do it. HDD manufacturers really are slashing warranty lengths (yes I know reds would have 3 year warranties, still bad).
