While making a few preliminary testing observations I noticed that the Seagate ST3750330AS burst rate seemed to be abnormally low. At first I couldn't discern why this was but after a little more poking around I discovered the drive was operating in SATA I mode. To switch it to SATA II mode meant removing the world's smallest jumper that was so tiny and pushed to the back of the block I had completely missed it in my earlier visual drive inspection, but taking the jumper off solved the low burst rate situation.
