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 480GB Crucial M500 solid state drive produced speeds up to 494.42 MB/s for reads and 423.62 MB/s writes. These results indicate that compressed data transfers move as quickly as uncompressed data on the Crucial M500. Single-threaded 4K IOPS performance tests deliver 22.78 MB/s read and 62.01 MB/s write, while the 64-thread 4K reads recorded 337.65 MB/s and write performance was at 306.33 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 480GB Crucial M500 SSD outperformed most other recently-released solid state drive products - primarily due to the larger NAND density and overall storage capacity (others SSDs tested are 240GB). Nevertheless, the Crucial M500 solid state drive easily surpassed previously-tested Micron/Crucial SSDs.
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.
