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 Samsung T3 portable solid state drive produced 435MB/s for sequential reads and 432MB/s for sequential writes. The 4K-64 thread test we concentrate on in this benchmark produced only 86MB/s reads and 110MB/s writes.

The chart below summarizes AS-SSD 64-thread 4KB IOPS performance results among a variety of enthusiast-level SSDs. The MU-PT500B returns a very low score relative to the internal SSDs that comprise the remainder of the chart.
In the next section, Benchmark Reviews tests transfer rates using ATTO Disk Benchmark.
