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.
Beginning with sequential read and write performance, the ADATA S599 SandForce SF-1200 Solid State Drive produced a 207.0 MB/s read speed, but only a 130.6 MB/s write. ADATA's own in-lab test results produced 207.5 and 131.8 MB/s read and write performance, which validates our own results.
Conversely, 4K IOPS performance swings in the opposite direction, with 16.1 MB/s read and 50.1 MB/s write. ADATA's lab was able to produce 20.7 and 56.9 MB/s read and write IOPS, which is notably higher than our results using the same system hardware.
Access time is one area that draws our attention, as the S599 SSD we received produced 0.24 ms read response times and 0.29 ms write times. ADATA's lab produced 0.08 and 0.23 ms response times, which are significantly lower. Keep an eye on read results, as we experience at least one other test that widely fluctuates test results.
AS SSD Benchmark also includes a file-copy tool for measuring transfer time and speed. Using the ADATA S599 SSD attached to the Intel ICH10 Southbridge in ACHI mode, our results produced a high of 94 MB/s and a low of 84.1 MB/s, In comparison, ADATA produced a high of 154.4 and low of 118.1 MB/s in their test lab - which is designed to generate maximum test results.
In the next section, Benchmark Reviews tests transfer rates using ATTO Disk Benchmark.
