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 OCZ Trion 150 solid state drive produced good results: over 464MB/s for sequential reads and an outstanding 529MB/s for sequential writes. The 4K-64 thread test we concentrate on in this benchmark produced a somewhat disappointing 131MB/s reads and 314MB/s writes.
OCZ Trion 150 Results
The chart below summarizes AS-SSD 64-thread 4KB IOPS performance results among a variety of enthusiast-level SSDs. While the write results were good, the read results placed this drive at the bottom of the chart.
In the next section, Benchmark Reviews tests transfer rates using ATTO Disk Benchmark.
