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 PX-256M6M's random read and write speeds, random access times and the number of operations per second.
The PX-256M6M performed very well when benchmarked with HD Tune. The drive had average read and write speeds of 497.6 MB/s and 404.2 MB/s, respectively, and a burst rate of 381.7 MB/s when reading.
The PX-256M6M didn't disappoint when doing random reads and writes. When writing 4KB blocks, the drive reached 20,040 IOPS and had an average speed of 78.283 MB/s. The PX-256M6M was even faster when reading, reaching 22,988 IOPS with an average speed of 89.799 MB/s.
