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 are looking at the 4K and 4K NCQ performance. This is where we start to see differences between the 25nm IMFT synchronized and a synchronized drives. Since CDM is a synthetic benchmark the results are exaggerated a bit because we are hitting this area a lot harder than you normally would in the real world. I'll explain more on the final page.
I ran this test on three different systems; one based on P67 and two based on Z68. In all of the tests the Corsair Performance 3 hit a brick wall abruptly around 140MB/s. It didn't really matter how many commands we sent to the drive, 140MB/s was the stopping point.
