Use smaller HDDs, or if cost is not a big issue just use the faster
portions of the big HDDs.

The smaller HDDs are about the same speed as the big ones of the same model
range- the bigger ones just have more platters.

But the bigger ones allow you to throw away slower space. By using just the
faster portions (the outer edges) you can reduce seek time by a few
milliseconds, and keep throughput in the higher bands.
