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 SX8000's random read and write speeds, random access times and the number of operations per second.

The SX8000 performed relatively well when benchmarked with HD Tune. The drive had average read and write speeds of 1701.9 MB/s and 458.6 MB/s, respectively, and a burst rate of 564.0 MB/s when reading.

The SX8000 didn't disappoint when doing random reads and writes. When reading 4KB blocks, the drive reached 43,662 IOPS and had an average speed of 170.556 MB/s. It was even faster when writing, reaching 58,682 IOPS with an average speed of 229.227 MB/s.
