AS SSD:

AS SSD is a benchmark designed specifically for solid state drives. The application contains five synthetic tests which are used to determine the sequential and random read and write performance of a drive.

AS SSD also includes a copy benchmark. This test copies an ISO (two large files), program (many small files) and game (small and large files), returning the speed and duration of each.

HD Tune Pro 5.00:

Next, I ran a series of tests using HD Tune Pro. This hard disk utility measures a drive's performance by testing its sequential read and write speeds as well as its access time, burst rate and CPU usage. For this review, I'm also going to use it to benchmark the Gold S31's random read and write speeds, random access times and the number of operations per second.

The Gold S31 performed relatively well when benchmarked with HD Tune. The drive had average read and write speeds of 487.8 MB/s and 419.7 MB/s, respectively, and a burst rate of 431.2 MB/s when reading.

When reading 4KB blocks, the Gold S31 reached 21,120 IOPS and had an average speed of 82.501 MB/s. The drive was faster when writing, reaching 24,737 IOPS with an average speed of 96.630 MB/s.
