Western Digital Red WD40EFRX 4TB Review (Page 6 of 11)

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 WD40EFRX 4TB come in? With an average read speed of 147.9MB/s, and tested random access time of 12.8ms, it is, by no doubt, fast. But how does it compare against the competition? Interestingly, the 5,900 RPM Seagate was actually the fastest of the trio in this test, with an average read speed of 166.8MB/s. The 7,200RPM Deskstar NAS came in at 158.0MB/s. That said, with the highest rotational speed in the class, the Hitachi did the best with a random access time of only 11.7ms; compared to Seagate's 14.9ms. It is actually quite impressive how the Western Digital, featuring the lowest RPM of all the drives, can achieve such low latency.
