CrystalDiskMark is disk benchmark software that allows us to benchmark 4K and 4K queue depths with accuracy.
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.
Overall we see really nice performance. Write performance does not scale beyond 4K QD1, but 99% of the time, a mainstream user isn't going to exceed 4K QD1 anyway.
Here we see our Ultra Plus array is faster than the Seagate 600 array on our chart. Both arrays utilize essentially the same NAND, but in this scenario, the Ultra Plus array has a slight edge, despite being powered by a controller with half the amount of channels.
The overall write performance of our Ultra Plus array is pretty much on par with the Chronos and Extreme II arrays. Compression is holding back the Chronos arrays performance and the Extreme II arrays performance is being restrained by capacity limitations.
