Western Digital Scorpio WD2500BEVS 2.5-inch SATA HDD
HD Tach Results
The four HD Tach metrics that we sampled for each drive are Random Access, which is largely dependent on spindle speed of the drive, Read Average, Write Average and Burst Read throughput. Read and Write Average scores are what we would consider the most meaningful to the end user. On the other hand, Burst Read is typically tied to a drive's on-board caching and SATA interface speed.

On paper, the Toshiba MK1032GSX is only really bested by the Scorpio WD2500BEVS in the capacity department. The Scorpio WD2500BEVS is a much newer drive, but we are still surprised to see just how much better it performs than the Toshiba MK1032GSX, which is made more evident by the HD Tach results. In addition, we are glad and impressed to see that the Scorpio WD2500BEVS doesn't get a serious beatdown from the WD5000KS, which has a big advantage over the Scorpio WD2500BEVS.
