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 a recent announcement the makers of CDM stated that they were making the 1000MB test the default benchmark so we have changed over from the 100MB test and started using the 1000MB test in our reviews.
USB does not take advantage of NCQ so queue depths do nothing for USB 2.0 or 3.0 performances. Here we do get a chance to see the 4K numbers that are on par with other platter based external drives. If the Touch were to use a solid state drive the 4K performance would increase significantly.
