If the logical drive contains critical data, you can set a high modification priority to keep the
time of a critical state (for example, after losing a disk) as short as possible, even if this affects
the system performance during the modification process.
The following modification priority rates are available:
Lowest
Low
Medium
High
Highest
Note: The lowest priority rate favors system performance, but the modification operation
takes longer. The highest priority rate favors the modification operation, but system
performance might be compromised.
To change the modification priority, perform the following steps:
1. Select a logical drive, right-click it, and select Change  Modification Priority.
2. Make sure that the correct logical drive is selected, and set the new Modification Priority
value, as shown in Figure 9-26.

3. Click OK and then Yes in next window to confirm this change.
4. You will then see the completion window as shown in Figure 9-27
