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 uses incompressible data in these tests so the incompressible data performance is under the microscope. The 4K single queue read speed is just over 25MB/s, this is lower than just about everything else on the chart including LSI SandForce drives like the Intel 520, another drive that slows when working with incompressible data.
The 4K single request write performance is also lower than just about everything on the chart. We suspect the drive is performing background operations while we were running these tests. The Anvil loads are quite significant and the drives get beaten up pretty good. Still, we run the same tests, in the same order for each drive.
