AS SSD:
AS SSD is a benchmark designed specifically for solid state drives. The application contains five synthetic tests 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 M9PG Plus' random read and write speeds, random access times and the number of operations per second.

The M9PG Plus performed relatively well when benchmarked with HD Tune. The drive had average read and write speeds of 2499.5 MB/s and 1172.9 MB/s, respectively.

When writing 4KB blocks, the M9PG Plus reached 35,039 IOPS and had an average speed of 136.874 MB/s. The drive was even faster when reading, reaching 39,846 IOPS with an average speed of 155.652 MB/s.
