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.
We use CDM to look at the 4K and 4K Queue Depth performance and the QD 32 on the Vertex 2 has me a bit baffled. The Vertex 2 is running the same numbers as the other SF-1200 drives, so that is fine, but the OWC Mercury just trots away from the SandForce pack. We were expecting to see the Vertex 2 do the same thing, but our expectations didn't line up with reality this time.
When it comes to 4K write speeds the Vertex 2 stayed with the SandForce pack and this time the A-DATA S599 was able to show a bit of dominance. IOPS is a bit different than transfer speeds, but in the next test we will start to see some real world performance numbers and leave these synthetics behind.
