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 5.75:
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 980 PRO's random read and write speeds, random access times and the number of operations per second.

The 980 PRO performed relatively well when benchmarked with HD Tune. The drive had average read and write speeds of 4,788.8 MB/s and 2,201.9 MB/s, respectively.

When writing 4KB blocks, the 980 PRO reached 40,933 IOPS and had an average speed of 159.896 MB/s. The drive was even faster when writing, reaching 42,506 IOPS with an average speed of 166.040 MB/s.
