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 SU750's random read and write speeds, random access times and the number of operations per second.

The SU750 performed relatively well when benchmarked with HD Tune. The drive had average read and write speeds of 469.4 MB/s and 398.9 MB/s, respectively, and a burst rate of 123.9 MB/s when reading.

When reading 4KB blocks, the SU750 reached 9,951 IOPS and had an average speed of 38.871 MB/s. The drive was considerably faster when writing, reaching 28,868 IOPS with an average speed of 112.767 MB/s.
