AS-SSD Benchmark

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 transfer performance, the OCZ Octane solid state drive produced speeds up to 492.68 MB/s for reads and 348.87 MB/s writes. Because this benchmark uses compressed data, sequential file transfer speeds are reported lower than with other tools using uncompressed data. For this reason, we will concentrate on the operational IOPS performance for this section.

Single-threaded 4K IOPS performance tests deliver 23.31 MB/s read and 37.65 MB/s write, while the 64-thread 4K reads recorded 130.57 MB/s and write performance was 50.87 MB/s.

AS-SSD 64-thread 4KB IOPS performance results are displayed in the chart below, which compares several enthusiast-level storage products currently on the market. In these 64-thread 4KB IOPS performance tests the OCZ Octane series did not outperformed many other SSDs, but did surpass the older Indilinx Barefoot series. The chart below is sorted by total combined performance, which helps illustrate which products offer the best operational input/output under load:

In the next section, Benchmark Reviews tests transfer rates using ATTO Disk Benchmark.
