SSD Performance Atto Disk Benchmark

Atto Disk Benchmark

ATTO is a freeware utility that offers you the ability to test a drive using a variety of different parameters. We test using an I/O size of 4KB to 1MB, a 256MB file size, and a queue depth of 10. Aside from a strange blip in the 256KB 'Read' test (where speeds dropped off by approximately 14%), we see performance in the read tests consistently and a fair way above that of the old Seagate drive. At lower I/O sizes, the difference is significantly less marked. I am not sure of the cause of this dip in performance. I can only imagine it is throttling, as the phenomenon was repeated with a further two runs of the benchmark.

Note that in the 'write' tests, the difference between the two drives is significantly closer, so much so that I would call this a draw. Before we go any further, however, look at that T5... it is so far out ahead of both the Seagate drive and the PD400, that it is barely competition. I mean, it should be, given that its RRP is just under double that of the Seagate drive, and over 3 times that of the PD400. Even this early on, I am already starting to think that a shade under £60 GBP is a pretty damned good deal! Next, we move onto a well-known test. Crystal Disk Mark.
