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 RevoDrive X2 PCI-E Solid State Drive produced 691.41 MB/s read speed and 279.44 MB/s write performance, compared to 393.05 MB/s read and 185.54 MB/s write on the 120GB RevoDrive. 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 26.66 MB/s read and 62.98 MB/s write, which is considerably higher than a single SandForce-driven SSD and still among the highest results we've recorded. 64-thread 4K reads recorded 418.64 MB/s while write performance was 257.61 MB/s... both earning the OCZ RevoDrive X2 SSD a spot among the top performance results in our charts. This compares well against the original RevoDrive with 221.92 MB/s reads and 170.45 MB/s writes.
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 that two separate SandForce SF-1200 SSDs in RAID-0 produced, the OCZ RevoDrive and RevoDrive X2 offer exceedingly impressive read performance and heavily outperform in write operations.
In the next section, Benchmark Reviews tests transfer rates using ATTO Disk Benchmark.
