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 the 4K performance and how well a drive is able to take advantage of NCQ. Here we see the 128GB C300 reading at nearly identical rates as the SF-1200 controlled drives, but a little slower than the 256GB C300.
The standard 4K write test has the 128GB C300 running a little slower than the SF-1200 drives, but once you get into queue depths both controllers appear to be pretty equal. The 256GB C300 does manage to outperform both the 128GB C300 and SF-1200 drives in 4K and 4K queue depth tests.
