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 Radeon R7's random read and write speeds, random access times and the number of operations per second.

The Radeon R7 didn't do as well as I had expected when benchmarked with HD Tune. The drive had average read and write speeds of 287.1 MB/s and 345.8 MB/s, respectively, and a burst rate of 354.5 MB/s when reading.

The Radeon R7 didn't disappoint when doing random reads and writes. When writing 4KB blocks, the drive reached 19,271 IOPS and had an average speed of 75.281 MB/s. The Radeon R7 was slightly faster when reading, reaching 19,543 IOPS with an average speed of 76.343 MB/s.
