Speed is impressive on this particular variant ofWD's performance-oriented hard disks. Being a single-platter drive with one of the highest data densities on the marŽket, shows in the numbers it puts up. The 16 MB cache helps too. In Everest UltiŽmate's disk benchmarking tool, the WD hit an average of 86.3 MBps in the random write test, which was the fastest in this comparison. Random read averaged at 86.6 MBps, which is again very fast for this class of hard drives. Just about every test showed up this drive in favorable light, including PC Mark, WinRAR, and linear read and write operations.

In our real world simultaneous multiple file read-write test, the WD took 988 secŽonds for the task. After two hours of stress testing, the WD was still not too hot to the touch, and actually produced the least temperatures measured in this comŽparison - helped along by the single-platter design, no doubt. A hard drive that runs cooler, usually allows you to maintain lower overŽall temperatures inside your computer cabinet. The one and only place where this drive falls behind, is the averŽage read access times, where its 16.39 ms score is slightly less than that of the Seagate entry. If you go out to buy this drive, do make sure to look for the speCific model variant on the label (00B3AO).
