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 look at 4K performance and 4K NCQ performance. This is where things really started to get interesting in our testing. The 4K results were quite a bit lower than the 120GB Vertex 2 and this lower performance scaled all the way up to the 32 depth with the AS602 delivering around half the 4K read speeds when compared to the Vertex 2.
Nearly the same thing happened with the 4K write tests, but this time the AS602 had a difficult time with a single command. We'll have to keep an eye on the real world performance testing to see how this equates to real world speeds.
