This is accomplished bycausing command reordering to be done on the drive.In order to make use of NCQ, the feature must be enabled at both the driveand the controller. You can enable support for NCQ on a per-unit basis, asdescribed below.You can see whether NCQ is supported and enabled for a particular drive inthe Drive Details window. For details, see “Drive Details window” onpage 196.Note: Not all drives support NCQ. If a drive does not support NCQ, the policysetting for the controller is ignored.
