Background Task Priority:
The Background Task Priority indicates how much time and system resource the RAID

subsystem allows user to choose the background task priority (High 80%, Medium 50%,

Volume Set access. For high R A I D s u b s y s t em performance, specify a low value.
JBOD/RAID Configuration:
The RAID subsystem supports JBOD and RAID configuration.
SATA NCQ Support:
NCQ is a command protocol in Serial ATA that can only be implemented on native Serial
ATA hard drives. It allows multiple commands to be outstanding within a drive at the
same time. Drives that support NCQ have an internal queue where outstanding
commands can be dynamically rescheduled or re-ordered, along with the necessary
tracking mechanisms for outstanding and completed portions of the workload.
Disabled or Enable the SATA NCQ function.
