Assigns the amount of importance that UltraTrak100 gives to
rebuilding/synchronizing data in the background. A High setting assigns most of
UltraTrak100’s resources to the rebuild process at the expense of responding to
ongoing read/write data requests by the operating system. A Low setting gives
priority to ongoing read/write data requests by the operating system at the
expense of the rebuild/synchronization process and will typically result in longer
rebuild/synchronization times. The default setting is High. To set the Rebuild/Sync
priority, go to the Configuration menu and select Configure Array; then select
Advance Features and choose Rebuild/Sync Pri.
