Our Test Systems and HD Tach

To test the new WD Velociraptor, we used a system built around an Intel Core 2 Extreme QX6850 (3 GHz) processor and Asus P5E3 Premium X48-based motherboard.  The test system was also outfitted with 2GB of DDR3 RAM, an LG optical drive, and a GeForce 8800 GTX. The operating system (Windows Vista Ultimate 32-bit) was installed on a separate WD Raptor 74GB drive, and all of the comparison drives were completely blank during testing.

HD Tach v3.0.1.0

We began our testing with Simpli Software's HD Tach, which is described on the company's web site as such: "HD Tach is a low level hardware benchmark for random access read/write storage devices such as hard drives, removable drives (ZIP/JAZZ), flash devices, and RAID arrays. HD Tach uses custom device drivers and other low level Windows interfaces to bypass as many layers of software as possible and get as close to the physical performance of the device possible."


As you look through the performance data, please pay special attention to the graph headers, as lower scores indicate better performance in some tests. As you can see, the new WD Velociraptor smokes all of the other drives we tested in every part of the HD Tach test suite, with the exception of CPU utilization.  While the WD Velociraptor had the highest CPU Utilization of the bunch, it was also clearly the fastest drive of the bunch.
