About HD Tach 22.214.171.124
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 450 256GB 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 315.5MB/s according to HD Tach in single disk configuration, this is the about average from our experience. The highest scoring SSD in HD Tach here at APH Networks is SanDisk's Ultra Plus 256GB we have reviewed a while back. Normally, we expect a SATA 6Gb/s SSD to crack about 300MB/s to be considered the acceptable baseline. Compared to the OCZ Vector 256GB, again, the "Vector Lite" Vertex 450 slotted just beneath its bigger brother's 329.0MB/s score.
