Page 6 - Benchmark: HD Tach

About HD Tach

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.

Now, it is the time for good old HD Tach. While HD Tach is more of a 'drag race' than a clear indication of real life performance, and has been around for a really long time, it is an excellent storage performance reference between hard drives for more than the last decade. Back in the days, if your average speed exceeded 60MB/s, you have a seriously fast drive. Where does the Western Digital Red Pro WD4001FFSX 4TB come in? With an average read speed of 166.5MB/s, and tested random access time of 9.9ms, it is, by no doubt, fast. But how does it compare against the competition? Interestingly, the 5,900 RPM Seagate was actually, on average, a hair faster in the same test, with an average read speed of 166.8MB/s. The 7,200RPM Deskstar NAS came in at 158.0MB/s, while the regular Red WD40EFRX dropped in at 147.9MB/s. However, the Western Digital Red Pro WD4001FFSX 4TB's random access time is absolutely untouchable. The Seagate reported 14.9ms, while the WD40EFRX came in at 12.8ms. Even the HGST Deskstar NAS -- the former best -- was only able to achieve 11.7ms. The Western Digital Red Pro was simply impressive in this regard.
