Priority settings
The Universal RAID Utility uses three levels (High, Middle, and Low) to set or display the priority of background
tasks (Rebuild, Patrol Read, and Consistency Check) of RAID Controller, while the Off-line Utility uses
numerical value for them. The table below shows the correspondence between the numerical value ranges and
levels for each item.
