AS-SSD Benchmark

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.

Shown below are the results for three different high-capacity Seagate disk drives. The first is our featured product, the 4TB Seagate Desktop HDD ST4000DM000 (Four-Platter), which registered a 139 MB/s read speed and 135 MB/s writes at 5900 RPM. The Seagate Barracuda ST3000DM001 (three-platter) and Seagate Barracuda XT ST33000651AS (five-platter) each performed faster, as a direct result of their 7200 RPM platter rotations.
