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.
Beginning with sequential transfer performance, the OCZ Vector solid state drive produced speeds up to 506.14 MB/s for reads and 495.86 MB/s writes. Since the OCZ/Indilinx Barefoot 3 platform is not dramatically effected by the compressed data used in this benchmark, sequential file transfer speeds appear higher than SSDs that prefer uncompressed data. For this reason, we concentrate on the operational IOPS performance for this section.
Single-threaded 4K IOPS performance tests deliver 24.37 MB/s read and 70.79 MB/s write, while the 64-thread 4K reads recorded 356.20 MB/s and write performance was 304.24 MB/s. This is significantly better than all other SATA-based SSDs previously released.
AS-SSD 64-thread 4KB IOPS performance results are displayed in the chart below, which compares several enthusiast-level storage products currently on the market. In these 64-thread 4KB IOPS performance tests the OCZ Vector series outperformed all other previously tested SATA-based SSDs. The chart below is sorted by total combined performance, which helps illustrate which products offer the best operational input/output under load:
In the next section, Benchmark Reviews tests transfer rates using ATTO Disk Benchmark.
