About HD Tach 126.96.36.199
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 SanDisk Ultra Plus 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 436.9MB/s according to HD Tach in single disk configuration, it is definitely the highest number we have seen in any solid state drive. Normally, we expect a SATA 6Gb/s SSD to crack about 300MB/s -- but beating the 400MB/s mark is a whole different story. While it is probably not too advisable to compare drives with different controllers, it is interesting to see that the fastest single SandForce drive in this test, the Patriot Pyro SE 240GB, delivered 'only' 388.8MB/s.
