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 240GB OCZ Vertex 3 produced 505.67 MB/s read speed, and 282.84 MB/s write performance. The sequential file transfer speeds have traditionally been low with this benchmark tool for SandForce controllers because of data compression, so we will concentrate on the operational IOPS performance for this section.
Single-threaded 4K IOPS performance delivers 21.69 MB/s read and 61.58 MB/s write, while the 64-thread 4K reads recorded 164.88 MB/s and write performance was 221.39 MB/s... both earning the OCZ Vertex 3 a position ahead of other Sandforce-driven SSDs in our performance results chart below.
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.
