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 VX500's random read and write speeds, random access times and the number of operations per second.

The VX500 performed pretty well when benchmarked with HD Tune. The drive had average read and write speeds of 493.5 MB/s and 462.6 MB/s, respectively, and a burst rate of 249.0 MB/s when reading.

The VX500's random read and write performance was hit and miss when tested with HD Tune. While the drive reached 15,759 IOPS when writing 4K blocks, it achieved only 5154 IOPS when doing random reads.
