Thanks for the info!
Mostly went with CD6 since it seemed like the best I could buy that was readily available - for VM drives that shouldn't be that heavily written to.
Seemed to beat consumer drives, have PLP, and decently large sizes - I bought two from wiredzone, 7.68TB for $1161 each.
Was considering the Kioxia CD6 drives for a workstation build.
I've got the WS-WRX80E-SAGE-SE-WIFI mb.
I've heard that U.3 is different than U.2, but can't figure out what I'd need to connect these drives either to this board or to a standard m.2 slot.
