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.
CDM is our last synthetic benchmark and we use it to observe 4K and native command queuing performance. In its current firmware form the Vertex 3 is faster at 4K reads than the Vertex 2, but when you start adding command depth the Vertex 2 is a little faster. In most desktop situations there is very little NCQ going on, at least much less than found in enterprise workloads. It will be interesting to see what happens with more refined firmware releases.
Things change quite a bit with the NCQ writes. Here we see the Vertex 3 120GB drive pouncing on the Vertex 2 in all of the tests.
