SAFE Mode (RAID 1/Mirroring)
Safe mode is RAID 1 mode. In this state, two hard drives are
closely mirrored. The actual capacity of portable hard drive equals
to the smaller capacity one, storage speed is same.as a single
block of hard disk. The advantage of RAID 1 lies that any piece of
hard disk stored data losing, others can not lose, its weakness is
the capacity loss of hard drive is bigger.
For this reason the RAID 1 mode is the ideal storage solution for
very important material such as databases or personal data.
