More precisely, "Will they last as long as their mechanical counterparts?"
My home deployment (32TB, mostly static files, in 16+3 RaidZ3) is stuffed full of 2TB WD Reds and one of them has decided to turn up its toes - just outside the warranty period(*)
I'm seeing some oddities in the other Reds and looking wistfully at Samsung 860QVO as a replacement - Yes they're 3 times the price of a Red (or twice that of a Red enterprise) but the lower power draw alone is worthwhile, as long as they'll last 6 years in service (warranty is three).
For obvious reasons if I do changeout drives, I'll be doing it piecemeal, but I'm a little worried about the durability of the remaining Reds (Yes it's backed up, but restoring that much is best avoided even off LTO6 tapes)
The question is: Has anyone tested these out and come to conclusions about endurance vs normal ZFS home nas write patterns? Samsung are quoting 1440TBW, which seems a bit on the low side (320 times total disk capacity if I opt for a 4TB, 720 on a 2TB)
Other than the early years and cheapest drives (especially PATA dropin replacements) I've generally had pretty good success on SSDs but the QLC stuff is a new ballgame.
(*) it spins up when powered, then spins down & goes offline/unresponsive immediately - unless you send it a scsi inq during its spinup and catch it at the right moment.
Attempting to read off it, causes it to go offline - only 12 reallocated sectors (3 actual disk sectors) have shown up and it's well within spec on that or pending - was 12, now 49 - but with that kind of jump I've pulled it anyway.
(Happy owner of a nice Z30 setup at workplace and looking to replace that with another TrueNAS as it's hitting EOL)
