HD Tune v2.55

HD Tune runs through a set of tests similar to those of HD Tach on the previous page and determines maximum and average transfer rates, access times, and CPU utilization.

HD Tune v2.55

Once again, the WD Velociraptor decimates all of the other drives in every aspect of HD Tune testing, except for CPU utilization. The WD Velociraptor's minimum data transfer rate in particular was impressive in light of the performance of the reference drives, which includes the the recently released, and already very fast WD6400AAKS.  According to HD Tune, CPU utilization was more in-line with the other drives, but considering the Velociraptor's increased performance, higher CPU utilization is too be expected.
