Do you consider a motherboard’s onboard SATA controller to be a RAID card? It may be easy to assume that just because I am constructing a RAID array that I am using a RAID card, however this is not the case.
This is the motherboard in use:

The SATA controller is in native AHCI mode, no RAID functionality is enabled. As far as I am aware, there is no hardware RAID controller on the board, just the BIOS-assisted software raid which no-one should use IMHO.
Additionally, the firmware revisions appeared to be the same across all four drives. Do you think that a hardware revision without a firmware revision could have caused this issue, and the drive was indeed faulty?
I am still unsure that RAID-enabled drives will make a difference here. What differences other than TLER are present in, for example, a WD Red branded drive which you seem to be pushing me to purchase?
I know that WD Green drives will like to go to sleep often, however in these tests the drive never had a chance to spin down.
