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 120GB OCZ Revo PCI-E Solid State Drive produced 393.05 MB/s read speed, and 185.54 MB/s write performance. The sequential file transfer speeds have traditionally been low with this benchmark tool because of uncompressed data, especially with SandForce controllers, which is why we will concentrate on the operational IOPS performance for this section.
Single-threaded 4K IOPS performance delivers 23.21 MB/s read and 63.28 MB/s write, which is similar to a single SandForce-driven SSD but still among the highest results we've recorded. 64-thread 4K reads recorded 221.92 MB/s, while write performance was 170.45 MB/s... both earning the OCZ Revo SSD a spot among the top performance results in our charts.
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:
Compared to the 228/143 MBps 64-thread 4KB IOPS two separate SandForce SF-1200 SSDs in RAID-0 produced, the OCZ RevoDrive matches read performance and heavily outperforms in write operations.
In the next section, Benchmark Reviews tests transfer rates using ATTO Disk Benchmark.
