Hitachi's disk stuff was bought by WD. They are still running separately (making hitachi drives), but they are a WD company.

I'd open the chassis and see what you have in there.

Desktop (non-ES) drives will have issues with vibration. Other drives working in close proximity will cause latency issues for the heads. You will see this if you run "iosnoop -D" and watch the average latency on the reads.

If the drives aren't Hitachi, then you'll have higher latency relative to Hitachi Ultras. They are the best.
