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 NCQ performance. Since the JMicron controller doesn't take advantage of NCQ we see 4K performing at a steady 12MB/s.
The Kingston SSDNow V Series doesn't take advantage of NCQ for write tests either. Here we see performance at 4K holding steady at 13MB/s.
