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 transfer performance, the Intel SSD 520 Series solid state drive produced speeds up to 504.58 MB/s for reads and 298.28 MB/s writes. Because this benchmark uses compressed data, sequential file transfer speeds are reported lower than with other tools using uncompressed data. For this reason, we will concentrate on the operational IOPS performance for this section.
Single-threaded 4K IOPS performance tests deliver 21.70 MB/s read and 62.60 MB/s write, while the 64-thread 4K reads recorded 241.38 MB/s and write performance was 234.08 MB/s. All of these results were extremely similar to the fastest 6GB/s SandForce SF2281 SSDs we've tested.
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 Intel SSD 520 Series outperformed all other SSDs, even surpassing the OCZ Vertex 3 Max IOPS Edition. 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.
