OCZ ARC 100 240GB Review (Page 6 of 10)

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.

After running a quick format on the OCZ ARC 100 240GB, it is back to the races with this SSD, and quite literally too. HD Tach is more of a 'drag race' approach to testing storage devices, and it has been around quite a while. To answer the question posed in Queen's Bohemian Rhapsody, this testing is not the real life, but more of a synthetic situation. However, HD Tach has been a favorite among our testing suite, and thus it makes its appearance once again. Looking at the results, we can see a generally flat line across the graph. The average read speed works out to 249.7MB/s, which is more than 50MB/s behind the OCZ Vertex 460 240GB. In comparison, the OCZ Octane 512GB pulled in an average speed of 335.5MB/s. Normally we expect a SATA 6Gb/s SSD to hit the 300MB/s mark, so this is kind of disappointing. The fastest drive we have seen in this test is the SanDisk Ultra Plus 256GB, and unfortunately this still remains today. When it comes to burst speed, the ARC 100 is well ahead of the Octane 512GB at 425.7MB/s vs. 325.2MB/s. The Vertex 460 is still ahead of both of course at 456.2MB/s.
