SAFE Mode (RAID 1/Mirroring)
Safe mode is also known as RAID 1. 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.
