@Binder I believe in this case it's WD that's doing it wrong, and that's what I hold them accountable for. SMR is utterly inappropriate for drives that are going to live in a RAID. The failure mode people are complaining about with these is:
- WD markets them as NAS drives.
- The drives often (as in most of the time) can't successfully complete a RAID rebuild because they can't handle the expected level of throughput and IO.
- Ergo whatever WD said is wrong - they're *not* NAS drives.
