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.
Beginning with sequential read and write performance, the 256GB Crucial m4 SSD CT256M4SSD2 produced 402.21 MB/s read speed, and 263.46 MB/s write performance. This compares well against the new SandForce SF-2281 controller on the OCZ Vertex 3, which produced 505.67 MB/s read speed, and 282.84 MB/s write performance
Single-threaded 4K IOPS performance delivers 19.73 MB/s read and 57.70 MB/s write, nearly matching the OCZ Vertex 3 with 21.69 MB/s read and 61.58 MB/s write. The 64-thread 4K reads recorded 158.24 MB/s and 211.48 MB/s writes, compared to 164.88 MB/s and 221.39 MB/s for the OCZ Vertex 3.
Displayed in the chart below, the 64-thread 4KB IOPS performance results for several enthusiast-level storage products helps to illustrate which products offer the best operational input/output under load:
In the next section, Benchmark Reviews tests transfer rates using ATTO Disk Benchmark.
