CrystalDiskMark is a disk benchmark software that allows us to benchmark 4K and 4K queue depths with accuracy.
* Sequential reads/writes
* Random 4KB/512KB reads/writes
* Text copy
* Change dialog design
* internationalization (i18n)
Note: Crystal Disk Mark 3.0 Technical Preview was used for these tests since it offers the ability to measure native command queuing at 4 and 32.
In CDM we look at 4K and NCQ performance. The Agility 3 has a lower 4K IOPS rating than the Vertex 3 and the differences show up in these tests. Here we see the Agility 3 running behind the Vertex 3 in all the 4K tests.
When it came to a straight 4K write, the Agility 3 was actually a little faster than our Vertex 3, but when commands were stacked the Agility 3 was a little slower.
