OCZ Vertex 2 100GB SandForce SF-1200 SSD ReviewFri, May 14, 2010 - 12:00 AM
HD Tach v18.104.22.168
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.
Benchmark Results: The OCZ Vertex LE 100GB SSD was able to reach 245MB/s read and 204MB/s write. The random access time and CPU utilization were really low, which is what we like to see on SSDs.
Comparison Chart: The OCZ Vertex 2 100GB and Vertex 2 LE 100GB SSDs were nearly identical in performance as they use the same brand of controller. All of the drives were benchmarked on the Marvell SATA 6Gbps controller in order for the testing to be fair in all of the benchmarks as some of the drives run on a SATA III interface. The random access times for all of the drives were 0.1 ms or lower, so nothing significant to see there.
