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

The 970 EVO Plus performed relatively well when benchmarked with HD Tune. The drive had average read and write speeds of 2442.2 MB/s and 501.6 MB/s, respectively, and a burst rate of about 543.9 MB/s when reading.

When reading 4KB blocks, the 970 EVO Plus reached 28,398 IOPS and had an average speed of 110.932 MB/s. The drive was even faster when writing, reaching 29,718 IOPS with an average speed of 117.088 MB/s.
