AS-SSD Benchmark Test Results
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. Because this software receives frequent updates, Benchmark Reviews recommends that you compare results only within the same version family.
This purpose of this section is to illustrate sequential file transfer speeds and demonstrate operational IOPS performance using AS-SSD Benchmark. For reference, we first tested the OCZ Rally-2 Turbo USB-2.0 flash drive which produced 27.9 MB/s read and 24.8 MB/s write speeds. With the Super Talent RAIDDrive ST3U64SRK attached to the Intel ICH10 USB-2.0 controller, this flash drive produced 33.2 MB/s read and 26.8 MB/s write speeds.
Stepping up to SuperSpeed USB-3.0 using the NEC-D720200F1 controller, the Super Talent RAIDDrive produced an impressive 156.3 MB/s read and 72.7 MB/s write speeds. These results are getting closer to the manufacturers suggested maximum speeds of 320/180 MB/s, but we haven't applied Super Talent's RAIDDrive RAID-0 software yet.
Once the 'STT USB Composite Device' and 'STT USB 3.0 Miniport' software has been installed, the Super Talent USB-3.0 RAIDDrive operates in a RAID-0 twin SSD array. AS-SSD produced 225.6 MB/s read and 103 MB/s write, both of which are impressive, but not quite reaching the advertised 320/180 MB/s read and write speeds.
AS-SSD Benchmark is great for comparing 4K IOPS results tested with 64 concurrent threads, but it's good to have a second opinion for basic speed measurements. To approach this from a different angle, we've included ATTO Disk Benchmark results in the next section.
