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.

    It sucks, doesn’t it? When I saw that you bought WD Red, I was heading out to the comments to alert you of that. Try to return your order, buy Seagate IronWolf instead and remember to never buy WD again.
