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 S80's random read and write speeds, random access times and the number of operations per second.

The S80 didn't do as well as I had expected when benchmarked with HD Tune. The drive had average read and write speeds of 320.3 MB/s and 304.0 MB/s, respectively, and a burst rate of 147.2 MB/s when reading.

The S80 didn't perform as well as the Ultra II when doing random reads and writes. When reading 4KB blocks, the drive reached 10,704 IOPS and had an average speed of 41.816 MB/s. The S80 was a bit faster when writing, reaching 14,931 IOPS with an average speed of 58.325 MB/s.
