SSD Performance HD Tach 3.0.4.0

HD Tach 3.0.4.0

HD Tach is a physical performance hard drive test that uses a special kernel mode VXD to get maximum accuracy by bypassing the file system.

The HD Tach sequential read test is a little bit different from other benchmarks. Most benchmarks create a file on the hard drive and test within that file. The problem is that modern hard drives use a zone bit recording technique that allows different read speeds depending on where the data is located. Data on the outside of the drive is much faster than data recorded on the inside.

Obviously for SSDs this is not an issue. We reach roughly 230MB/sec measured, for this particular test it's among the fastest we have ever seen for any storage device (not in RAID). And yes .. we probably need to move towards a RAID controller soon as our Intel ICHR10 SATA2 controller is apparently slowly starting to become a limiting factor.

Here's a little test report of HDTach in both a long READ and WRITE sequence as well. Really fast results, write performance is as advertised by OCZ actually. That write performance is nearing 200 MB/sec, but heck yeah, it really shows what the storage unit is capable of, and that definitely is amazing for a product positioned as mainstream.
