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 5.75:
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 WD_BLACK SN770's random read and write speeds, random access times and the number of operations per second.

The P3 Plus performed relatively well when benchmarked with HD Tune. The drive had average read and write speeds of 5702.2 MB/s and 5240.1 MB/s, respectively.

When reading 4KB blocks, the P3 Plus reached 58,861 IOPS and had an average speed of 229.928 MB/s. The drive was even faster when writing, reaching 61,781 IOPS with an average speed of 241.335 MB/s.
