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.
Normally we use CDM to measure 4k performance and scaling with NCQ, but since CDM uses incompressible data it shows us another issue with the asynchronous flash drives, poor incompressible data performance. Here we see that the async Pyro reads this type of data at about half the rate of the Vertex 3 with synchronous flash.
The same is true when writing incompressible data to the drive. The Pyro hits a brick wall right around 140MB/s when writing data and it doesn't matter how many commands you write the data with, the wall is there and there is no getting past it.
