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.
There is a reason why Toshiba Toggle flash is used on many of the enterprise variants of SandForce SF-2000 series drives and you can see it here. When stacking up commands with NCQ the flash is able to put up very large performance numbers. Here we see the Mercury Extreme Pro 6G hammering everything else on the chart in the 4K QD:32 test.
CDM uses incompressible data and that is why we aren't seeing the big 500+MB/s numbers that you see in the 0 fill tests. The write performance is very good, but the flash does perform sequential transfers of incompressible data a little slower than the INFT 25nm sync flash drives.
