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 5.75:
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 ATOM 30 kit's random read and write speeds, random access times and the number of operations per second.

The ATOM 30 performed relatively well when benchmarked with HD Tune. The drive had average read and write speeds of 2,546.6 MB/s and 1,812.8 MB/s, respectively.

When reading 4KB blocks, the ATOM 30 reached 33,920 IOPS and had an average speed of 132.501 MB/s. The drive was even faster when writing, reaching 35,330 IOPS with an average speed of 138.011 MB/s.
