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 256GB Premier SP610 solid state drive produced speeds up to 509.06MB/s for reads and 285.35MB/s for writes. While the read speeds were among the highest we’ve ever tested, the write speeds lagged far behind. Single-threaded 4K IOPS performance tests delivered 26.68MB/s reads and 67.16MB/s writes, while the 64-thread 4K read test recorded 293.28MB/s with write performance at 254.11 MB/s.
256GB Premier SP610 SSD AS-SSD Results
The chart below summarizes AS-SSD 64-thread 4KB IOPS performance results among a variety of enthusiast-level SSDs. The ADATA SP610 turns in a little over half the read performance of the reigning champion, the Kingston HyperX Savage, but almost 90% of the write performance. 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.
