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 OCZ Vertex 3.20 solid state drive produced speeds up to 498.77 MB/s for reads and 317.22 MB/s writes. Single-threaded 4K IOPS performance tests deliver 17.04 MB/s read and 64.87 MB/s write, while the 64-thread 4K reads recorded 181.96 MB/s and write performance was at 232.56 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 OCZ Vertex 3.20 SSD easily surpassed the 120GB version, but was still outperformed by several recently-released solid state drives.
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.
