HD Tune Benchmarking
Next up we used HD Tune 2.55 to test the drives. HD Tune is somewhat similar to HD Tach in the tests it runs but uses its own methods and workload to arrive at performance results.
The HD Tune results show the WD Green Power 2TB only being bested by the Seagate 7200.11 in the transfer rates benchmark among the standard retail desktop drives. In the Random Access Time test, the WD GP 2TB turned in an impressive 12.8ms which was confirmed by multiple test runs. The Green Power 2TB drive performs especially well here and even under a full load uses less power than other retail drives, as you'll see later.
