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 may be 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 480GB SX930 solid state drive produced speeds up to 510.45MB/s for reads and 443.83 for writes. This write speed distinguishes the SX930 from ADATA’s SP6x0 line, which only produced 285.35MB/s for writes. Both the read and write speeds are very competitive, but the drive’s performance in the “4K” tests is less so, coming in below the figures turned in by its value-oriented cousin SP610.

The chart below summarizes AS-SSD 64-thread 4KB IOPS performance results among a variety of enthusiast-level SSDs. The ADATA SX930 ranks below even value-oriented drives like the Crucial BX100 here, and this is a little disappointing considering that it’s marketed as a performance drive.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.
