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 500GB Crucial BX100 solid state drive produced speeds up to 513.03 MB/s for reads and 424.49 MB/s writes. Single-threaded 4K IOPS performance tests delivered 27.30 MB/s reads and 62.85 MB/s writes, while the 64-thread 4K read test recorded 271.49 MB/s with write performance at 273.43 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 500GB Crucial BX100 solid state drive may not have topped our benchmark results, but it did offer twice the capacity of other drives for the same cost.
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.
