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.
AS-SSD Benchmark uses compressed data, so sequential file transfer speeds may be reported lower than with other tools using uncompressed data. For this reason, we will concentrate on the operational IOPS performance in this section.
This benchmark provided a surprise: although the performance results were great with Toshiba’s native driver, the results for the 4K subsections of the test with the Windows driver were terrible…the lowest we’ve ever recorded, in fact.
OCZ VX500 Results
Compared to other SATA SSDs Benchmark Reviews has tested, the OCZ VX500 512GB drive turns in a solid mid-pack performance, although its writes are down about 30% from the chart-topping drives. Curiously, while its read results are much better than those of its entry-level Trion sibling, the latter’s write results on this benchmark are superior.
In the next section, Benchmark Reviews tests transfer rates using ATTO Disk Benchmark.
