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.
Here we are looking at 4K performance and 4K at two different queue depths. The SF-1200 is an 8 channel controller with 2 bit lanes. Only one is active at a time, but we still see great scaling with NCQ.
Everything is nearly identical until we get to the 4K: QD32 test. Here we see the 60GB Vertex 2 step up and hit one out of the ball park while the other drives were hitting triples.
NCQ is working on the VR, but with 4K numbers like that can you really consider a 1.5MB/s increase progress when compared to the SandForce SF-1200?
The write test shows identical performance for all of the Vertex 2 drives other than the 60GB model. Here we see what looks to be a brick wall at 100MB/s. Interestingly enough, it is still faster than the Intel X25-M G2 80GB drive.
