Note: Crystal Disk Mark 3.0 is not available to the public yet, but the Technical Preview does allow us to test 4K performance at queue depths of 4 and 32 in addition to 1. The current release Crystal Disk Mark only shows us QD 1.
In CDM we are looking at 4K performance and how it scales when commands are stacked using native command queuing. Here we see good NCQ scaling on the SATADIMM, but the overall 4K performance is a little lower than what we have on the Vertex 2.
When it comes to 4K writes the SATADIMM is down a little to the Vertex 2 initially, but quickly takes the lead when commands are stacked up 4 and 32 deep.
