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 read and write performance, the 160GB Intel SSD 320 Series solid state drive produced 264.52 MB/s read speed, and 162.61 MB/s write performance. Because this benchmark uses compressed data, sequential file transfer speeds are reported lower than with other tools using uncompressed data. For this section, we will concentrate on the operational IOPS performance using compressed data. Single-threaded 4K IOPS performance delivers 19.39 MB/s read and 36.04 MB/s write, while the 64-thread 4K reads recorded 133.92 MB/s and write performance was 59.97 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. The chart is sorted by total combined performance, which 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.
