NOTE:

NOTE:

All data previously stored on the hard drive will 
be lost! Please back up all data to a separate 
storage before continuing.

RAID 1:

This mode allows the device to automatically 
copy data to 2 hard drives. It stores all data in 
duplicate to protect against data loss due to  
drive failure. It provides the highest level of data 
protection for critical data that you cannot afford 
to lose if a hard drive fails. The capacity is equal 
to the smaller of the two hard drives. Switching 
to this mode will prompt to initialize and format 
the hard disks. This will not work to create a 
mirror set from existing hard drives.

If one drive fails, the SAFE volume is still usable, but it is in a vulnerable state because its mirrored hard 
drive is inaccessible. When the offline drive comes back online, the appliance begins a rebuild process 
immediately to restore data redundancy. Although the volume remains available during the rebuild 
process, the volume  is susceptible to data loss through damage to the remaining drive until redundancy 
is restored at the end of the rebuild and verification process. Host access takes precedence over the 
rebuild process. If you continue to use the SAFE volume during the rebuild, the rebuild process will take 
a longer time to complete, and the host data transfer performance will also be affected.
