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 performance at queue depth (NCQ). The Toshiba controller delivers around 20MB/s 4K read speed, but still doesn't take advantage of NCQ.
The 4K write speeds were much better than the read, but NCQ is still not enabled on the Toshiba controller.
