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 get to look at the 4K and queue depth performance. These tests gave us the largest differences in performance when comparing the 90GB to the 120GB drives. The Corsair Force 90GB is still very fast when it comes to 4K performance, but here we see that the 120GB drives are quite a bit faster and that difference amplifies at queue depth.
The 4K write speeds are nearly the same as the larger drives and there wasn't much of a performance difference.
