We use CDM mainly for looking at 4k and NCQ on solid state drives. Platter drives have yet to catch SSDs in 4k performance, but we can still use the software to see how well native command queuing is working on a drive. Here we see that a single 4k hit delivers just under 1MB/s, but once we get to a depth of 32 the performance increases to around 2.3MB/s.

NCQ on the write side shows the 4k performance at nearly the exact same levels.
