Unless I'm mistaken, you're not using a RAID controller?

If you are not using a RAID controller then the processing resources of the computer are used to control the RAID. Once you do this, the performance bottleneck becomes the processor. A RAID card independently processes the RAID leaving the processor and GPU free to render the output.
