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.
The highest 4K QD1 read we've tested on this test system was 41MB/s. The Neutron GTX performs the same test at right around 30MB/s. Neutron GTX scales well though as the requests stack.
4K write performance scales well with additional depth. The single depth 4K-write speeds are right around 118MB/s.
