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 T5's random read and write speeds, random access times and the number of operations per second.

The T5 performed relatively well when benchmarked with HD Tune. The drive had average read and write speeds of 447.5 MB/s and 424.6 MB/s, respectively, and a burst rate of 204.0 MB/s when reading.

The T5 didn't perform nearly as well as the 850 EVO when doing random reads and writes. When reading 4KB blocks, the drive reached 13,188 IOPS and had an average speed of 51.517 MB/s. The T5 was slightly faster when writing, reaching 13,207 IOPS with an average speed of 51.591 MB/s.
