OCZ Apex Series 120GB SATA II SSD
HD Tach Benchmark
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."
Although the graph looks very erratic, with large peaks and valleys, the OCZ Apex Series drive put up some good scores in HD Tach. Its Read speed of over 169MB/s was the second fastest of the bunch, behind only Intel's SSD. But the OCZ Apex Series drive's write performance was the best overall, at over 117MB/s.
