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 Ultimate SU800's random read and write speeds, random access times and the number of operations per second.

The SU800 performed fairly well when benchmarked with HD Tune. The drive had average read and write speeds of 519.9 MB/s and 417.7 MB/s, respectively, and a burst rate of 370.5 MB/s when reading.

When writing 4KB blocks, the SU800 reached 17,964 IOPS and had an average speed of 70.174 MB/s. The drive was faster when reading, reaching 25,358 IOPS with an average speed of 99.055 MB/s.
