OCZ Synapse 64GB 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.

At this point of the review, as always, I have fired up HD Tach for some tests. While HD Tach is more of a 'drag race' than a clear indication of real life performance, it is an excellent storage performance reference, and has been our favorite benchmark long before drives even cracked the 50MB/s mark. One thing we must understand beforehand is the fact that HD Tach is not exactly the best program to evaluate a caching SSD and hard drive combination. But before you call any names, take a look at our results above. The first curve is purely 7200.10; benchmark a raw Seagate Barracuda of that generation, and these are the results you should expect. However, amazing things happened in the second and third run. With 32GB caching capacity, the Synapse actually dramatically improved HD Tach performance -- delivering an almost consistent 160MB/s read across the entire drive. Not only that; latency time is reduced to a mere 0.1ms. Nice.
