I have a black nvme tiered in storeMI with a WD Black 6TB. I get my first CPU core going between 80-100 percent. The system will hang for a few seconds, NIC dropps, and sometimes I get a BSOD with eventlog events related to an AHCI reset controller. This is not the boot volume. I read where users with a samsung nvme had the same issue but it was resolved with the samsung disk driver. WD seems to only allow the windows driver. Anyone using StoreMI with one of these drives? WD, is there some kind of driver available?
