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 4.61:

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

The 600 SSD performed very well when benchmarked with HD Tune. The drive had average read and write speeds of 484.3 MB/s and 424.2 MB/s, respectively, and a burst rate of 138.3 MB/s when writing

The 600 SSD didn't disappoint when doing random reads and writes. When reading 4KB blocks, the drive reached 19,372 IOPS and had an average speed of 75.673 MB/s. The 600 SSD was even faster when writing, reaching 21,201 IOPS with an average speed of 82.819 MB/s.
