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 ADATA XPG SX900 solid state drive produced speeds up to 507.71 MB/s for reads and 317.53 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 19.66 MB/s read and 62.85 MB/s write, while the 64-thread 4K reads recorded 186.50 MB/s and write performance was 236.46 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 ADATA XPG SX900-series did not outperformed many other SSDs, but did surpass the older Indilinx Barefoot and SandForce models. 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.
