So I posted not too long ago that I had a drive failure in my RaidZ pool. Ordered a replacement disk (WD RED, purpose built for NAS), and tried resilvering only to see this after a short while…

Turns out WD started pushing out a new disk technology called SMR, that’s slower, and fails when rebuilding RAIDs due to heavy write operations, and specifically marketed it towards NAS users? WTF Western Digital?!
Anyway, disk RMAd, and a replacement CMR disk is on the way. I’ll never buy WD drives again… Lesson learned the hard way.
Fair enough, I ask because nobody really mentions them but their backblaze stats seem good on a failure rate standpoint and they’re fast since they run at the full 7200rpm where others don’t. Though I have heard they’re noisy (pun intended).
I’ve always felt shucking drives to be a bit risky personally, moreso now.
If the price is $100 lower if I shuck them, then I will take the slightly inferior warranty.
I don’t really like 7200 RPM drives, but I don’t have a choice if I’m looking at bigger drives.
