While testing the drives we used a KINGWIN KF-1000-BK 3.5" Internal hot swap rack attached to one of the six ASUS P5Q-E onboard 3Gb/s SATA II ports. A hot swap utility was used that allowed us to spin down each drive and swap it out without rebooting.
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."
The Western Digital Green Power 2 TB delivers impressive results in HD Tach. The read/write, random access, and burst speeds are all great for a consumer hard drive, especially one that employs "Green Technology". It even turns in the best write results among all the drives except for the high performance WD Velociraptor.
