The 4 disks attached to the ahci driver should be using NCQ. The two
cmdk disks will not have NCQ capability as they are under control of
the legacy ata driver. What does your pool topology look like? Can you

You can also verify if your disks are NCQ

ide, instance #0 (driver name: ata)
cmdk, instance #0 (driver name: cmdk)
cmdk, instance #2 (driver name
