For a 1 disk setup, I'm seeing a tiny - possibly insignificant - improvement. There's no obvious regression, so I'll go ahead and mark verified.

[Test Case] Attach SSDs to the controller, and run fio with the attached configuration file (adjust disk names as appropriate). You should see a nearly 2x improvement.
