(Not applicable to SAS drives, only applicable to SATA drives that support
NCQ) SATA-2 drives support NCQ (Native Command Queuing), which can
result in increased performance for some applications, usually server-type
applications. In order to make use of Native Command Queuing, the feature
must be enabled at both the drive and the controller. Not all drives support
queuing.
The queuing values in this window indicate whether the feature is supported
and enabled at the drive. At the controller level, queuing is enabled or
disabled for all drives in a unit on the Controller Settings page.
