HD Tach Testing

Simpli Software's HD Tach is described on the company's web site as such: "HD Tach is a low level hardware benchmark for random access read/write storage devices such as hard drives, removable drives, 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 being tested."

Samsung 470 Series 256GB

Corsair Nova Series V128 128GB

Intel X25-M Gen2 80GB

OCZ Vertex 2 100GB

There are a couple of interesting things to note here. First, both the Samsung 470 and Corsair Nova Series V128 turned in almost identical numbers across the board. If this were a videocard review or just about any other component, we'd be looking for a bottleneck, but that wasn't the case here.

Secondly, Samsung's drive hardly blinked throughout testing, turning in read and write lines as flat as you're ever going to see in HD Tach. Credit goes not only to the custom controller, but the dual 128MB DRAM chips, where most other SSDs we've seen use 'just' one chip.
