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.
Beginning with sequential transfer performance, the Centon 480GB solid state drive produced speeds up to 516.89MB/s for reads and 464.16 for writes. Both of these sequential speeds are among the fastest we’ve seen recently. But a better “load test” for the drive is AS-SSD’s 64-thread section.
480GB Centon C-380 SSD AS-SSD Results
The chart below summarizes AS-SSD 64-thread 4KB IOPS performance results among a variety of enthusiast-level SSDs. The Centon SSD comes up a little short in the write category, which is something we’ve seen with the Phison controller on this test in the past. Read performance on the other hand is very good, if not quite up to the very best drives we’ve tested.
In the next section, Benchmark Reviews tests transfer rates using ATTO Disk Benchmark.
