Before there was a NAS drive line, WD Black could possibly be used for small RAID environments and we did list basic RAID support for the Intel controllers since they would account for the drives not having TLER. However, since WD Red has been released, WD Black was optimized for performance all references to RAID use removed.
I’m not saying that WD Black won’t work, as you have demonstrated, it just isn’t designed for that type of environemt and failures could occur more frequently in an environment the drive wasn’t designed for.
