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.
For years 40 MB/s was the goal for QD1 4K performance, but the 840 EVO products have pushed past 40 MB/s, and moved the goal to 50 MB/s. The EVO drives also scale well as the queue depth increases.
The 4K write IOPS scale well, and the QD1 performance is also one of the highest on the chart.
