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 3TB Seagate Barracuda XT hard drive produced 157 MB/s read speed, and 156 MB/s write performance. Single-threaded 4K IOPS performance delivers 0.68 MB/s read and 1.39 MB/s write, while the 64-thread 4K reads recorded 1.85 MB/s and write performance was 1.27 MB/s. These results fall well-below those of any solid state drive, but theye actually compare well against other mechanical storage products.
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:
In the next section, Benchmark Reviews tests transfer rates using ATTO Disk Benchmark.
