Mirroring Array Creation Options
When you create a RAID1 array, the synchronize option is checked
by default. (When you create a RAID 0/1 array,
the system will make the initialization automatically for you):
1. Initialize: Clear all data of the original disk and the mirror disk.
2. Synchronize: Copy all data of the original disk to the mirror disk
Also, you can select
synchronizing from the menu.
Note: Only RAID 1 and RAID 0/1 array can be synchronized.
