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

The VP performed relatively well when benchmarked with HD Tune. The drive had average read and write speeds of 515.1 MB/s and 429.0 MB/s, respectively, and a burst rate of 132.7 MB/s when reading.

When writing 4KB blocks, the VP reached 27,478 IOPS and had an average speed of 107.338 MB/s. The drive was slightly faster when reading, reaching 29,341 IOPS with an average speed of 114.617 MB/s.
