Alex Schepeljanski of Alex Intelligent Software develops the free AS SSD Benchmark utility for testing storage devices. The AS SSD Benchmark tests sequential read and write speeds, input/output operational performance, and response times. Because this software receives frequent updates, Benchmark Reviews recommends that you compare results only within the same version family.
Beginning with sequential read and write performance, the 120GB OCZ Vertex 2 Extended Solid State Drive produced 208.95 MB/s read speed, and 131.12 MB/s write performance. The sequential file transfer speeds have traditionally been low with this benchmark tool, especially for SandForce controllers, which is why we will concentrate on the operational IOPS performance for this section.
Single-threaded 4K IOPS performance delivers 19.62 MB/s read and 62.78 MB/s write, which is among the highest results we've recorded. Similarly, the 64-thread 4K reads recorded 123.47 MB/s while write performance was 116.00 MB/s... both earning the OCZ Vertex 2 Extended SSD a spot among the top results in our charts.
Displayed in the chart below, the 64-thread 4KB IOPS performance results for several enthusiast-level storage products helps to illustrate which products offer the best operational input/output under load:
In the next section, Benchmark Reviews tests transfer rates using ATTO Disk Benchmark.
