AS SSD:
AS SSD is a relatively new 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 WD Black SN750's random read and write speeds, random access times and the number of operations per second.

The WD Black SN750 performed relatively well when benchmarked with HD Tune. The drive had average read and write speeds of 2449.1 MB/s and 1545.6 MB/s, respectively, and a burst rate of 278.0 MB/s when reading.

When reading 4KB blocks, the WD Black SN750 reached 41,150 IOPS and had an average speed of 160.744 MB/s. The drive was even faster when writing, reaching 48,742 IOPS with an average speed of 190.400 MB/s.
