AS SSD:

AS SSD is a benchmark designed specifically for solid state drives. The application contains five synthetic tests which are 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 NQ100's random read and write speeds, random access times and the number of operations per second.

The NQ100 performed relatively well when benchmarked with HD Tune. The drive had average read and write speeds of 519.0 MB/s and 503.9 MB/s, respectively.

When reading 4KB blocks, the NQ100 reached 24,576 IOPS and had an average speed of 96.003 MB/s. The drive was faster when writing, reaching 30,819 IOPS with an average speed of 120.389 MB/s.
