I know several folks who bought these drives as NAS drives, for NAS use, when they were not all the same. Folks could have just bought SMR drives from WD, but specifically bought NAS drives.
Western Digital's denial, and the fact it took a class action lawsuit, were enough that WD no longer sells WD RED, only WD Red+ and WD Red Pro.
SMR drives don't work well for NAS'. SMR is useful for things other than NAS storage which is on all the time.
Rebuilding a NAS because things overlap so much takes a lot longer with SMR drives, compared to CMR. SMR drives used in NAS formation seem to fail more too.
Building any kind of NAS with SMR drives is asking for trouble and pain. I guess SMR drives could be proactively replaced, would need to factor that into the cost / tco.
Western Digital deceptively sold and charged a premium for the WD Red drives sold as NAS drives that were CMR, when they were not.
Western Digital didn't withhold anything about SMR being good or bad.
Western Digital confesses some WD Red Drives use SMR without disclosure:
