OCZ Vertex 3.20 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 giving the OCZ Vertex 3.20 240GB a clean format and ensuring alignment and everything is correct, I fired it up for some testing in HD Tach. While HD Tach is more of a 'drag race' than a clear indication of real life performance, it is an excellent storage performance reference among SSDs with the same controller, and has been our favorite benchmark long before hard drives even cracked the 50MB/s mark. With an average read speed of 381.5MB/s according to HD Tach in single disk configuration, again, this is only slightly behind the OCZ Vertex 3 Max IOPS 240GB at 383.4MB/s. Just for reference, the fastest SandForce drive we have ever tested in this test is the Kingston SSDNow V300 120GB at 400.9MB/s, with the record going to SanDisk's Ultra Plus 256GB at 436.9MB/s. Prior to this, the fastest SandForce based 240GB drive in this test, the Patriot Pyro SE 240GB, delivered 'only' 388.8MB/s.
