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're looking at 4K and native command queuing performance. The Neutron GTX 480GB 4K performance is very close to what we recorded on OCZ's Vertex 4 (Indilinx Modified Marvell) and Vertex 3 (SandForce SF-2281). Neutron GTX scales very well when the commands are stacked, up to 122MB/s at QD4 and 369MB/s at QD32.
The LSI SandForce SF-2281/2282 drives in 480GB or 512GB capacity size produce low 4K write numbers. At the bottom of the chart we have the OCZ Vertex 3 480GB and you can see the low 4K write speeds, the lowest on our list of large capacity drives. The Corsair Neutron GTX 480GB with a LAMD controller produces more than 5x the 4K write performance.
