RAID1 system

You can operate two drives of the same capacity and type independently of each other as a
RAID1 system or as a "System with 2 drives" (see "System with 2 drives (Page 70)").
An RAID1 system works on the principle of "data mirroring on two drives". In the event of a
defective drive the RAID1 system can continue to work on the remaining drive and thus
achieves a high level of availability.
