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.
Beginning with sequential transfer performance, the MyDigitalSSD BP4 Slim 7-series solid state drive produced speeds up to 503.46 MB/s for reads and 369.70 MB/s writes. It appears that the Phison controller prefers uncompressed data, so since this benchmark tool uses compressed test data we'll concentrate on operational IOPS performance in this section.
Single-threaded 4K IOPS performance tests deliver 25.83 MB/s read and 53.80 MB/s write, while the 64-thread 4K reads recorded 141.75 MB/s and write performance was 225.85 MB/s. These results are on-par with second-generation LSI/SandForce SF-2281 SSDs, such as the Intel SSD 335 or OCZ Vertex 3.
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 MyDigitalSSD BP4 Slim 7-series performed towards the upper-end of previously tested SATA-based 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.
