If you want to use the Serial ATA hard disk drives as Parallel ATA physical storage devices, keep the
default setting [IDE Mode].

that increases storage performance on random workloads by allowing the drive to internally optimize the
order of commands.

Serial ATA hard disk drives, set this item to [RAID Mode].
