That's interesting, I have a WD Black SN850 in my MNT Reform with ZFS on it and luckily haven't run into any issues with it, though I'm not stressing it in any kind of way. WD disks and ZFS go back a long way, when the Green HDD line first showed up in the late 2000s they caused a lot of headaches since ZFS expects to be in control & have a response when issuing requests where as the Green drive's firmware would be trying to conserve power, resulting in bogus errors.
