(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.
Link Supported and
Link Enabled. These fields show the fastest link speed that the disk drive supports and the current link speed.
Consult your disk drive manufacturer for information on how to interpret the SMART data. The SMART data meaning varies by disk drive manufacturer and model.
