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.

AS-SSD Benchmark uses compressed data, so 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 in this section.

Beginning with sequential transfer performance, the 240GB SanDisk Extreme II solid state drive produced speeds up to 507.17 MB/s for reads and 460.40 MB/s writes. Single-threaded 4K IOPS performance tests deliver 28.29 MB/s read and 61.35 MB/s write, while the 64-thread 4K reads recorded 349.46 MB/s and write performance was at 276.81 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 the 64-thread 4KB IOPS performance tests, the 240GB SanDisk Extreme II SSD easily surpassed much of the competition, but could not outperform the leading solid state drive storage solutions.

The chart below is sorted by total combined performance, which helps illustrate which products offer the best operational input/output under load:
