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 CMD we are looking at 4k performance and how a drive is able to scale 4k reads at two different native command queuing depths. The single Constellation.2 SAS drive scales very well and the results are then amplified when more drives are added to a RAID array.

The write test shows that NCQ doesn't play much of a factor when writing data to the single drive or RAID arrays.
