Are you interested in equipping yourself with one of the fastest SSD’s on the planet? If so, then OCZ’s Vertex 2 is the one you want to keep an eye on. Thanks to its tweaked SandForce SF-1200 controller, the Vertex 2 is the fastest SSD we’ve ever tested, dominating almost every single one of our tests.

Synthetic: HD Tune Pro 3.5, HD Tach RW3

HD Tune Pro 3.5

HD Tune has long been one of our favorite storage benchmarks, thanks in part to its ease-of-use, and its ability to deliver consistent results (which is obviously important). Since we are using HD Tune on storage devices that also house our OS, we’re unable to test the write performance, so here, we stick to both Read and Access Times.

Unlike the AS SSD read results, HD Tune does clearly like OCZ’s Vertex 2 SSD. Worth mentioning is that the Vertex Turbo does offer slightly better 512B and 4KB file size performance than the Vertex 2, at least with this program.

Yet again we show access times as these are the hallmark of solid-state drives, and I can’t underscore this point enough. The dirty state of the G1 leaves it with a particularly high result here, but even the G1 and other SSDs all put in results an order of magnitude better than the platter-based drive with small file reads.

HD Tach RW/3

HD Tach is a program similar to HD Tune, and although it hasn’t been updated in a few years, it’s still decent for testing SSDs. It offers a different method for calculating burst rates, as well as offering access time measurements below 0.1ms, which is unfortunately the limit for HD Tune. With a massive new program rewrite in the works, we look forward to seeing what the upcoming new version can do.

HD Tach’s age might be showing here, and we can only hope that the announced future rewrite of the program brings it up to date with storage technology. The Vertex 2 ranks in just above the old Summit drive, but given the best read results are held by a JMicron based drive and other similarly fast drives also fared poorly we aren’t going to give this test too much credence.

HD Tach is another program designed to measure platter-based drives (hence the downward curve in the image) but is capable of measuring access times below 0.1ms if the platform is up to the challenge. For the hard drive, the 13ms access latency is typical for a standard mechanical drive, but even a VelociRaptor would only decrease the latency to 7ms, a far cry from 0.1ms any SSD typically achieves. This clearly illustrates the drawback to RAIDing traditional mechanical drives.
