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 so we get our first real look at how the Ultra Plus compares to the drives with LSI SandForce SF-2281 controllers like the Intel 520. I'm still blown away about the four-channel Ultra Plus' performance.
When writing sequential data that is incompressible, the Ultra Plus has a lead of over 100MB/s on the Intel 520 240GB.
