What are the different RAID levels and what are they used for? ... RAID 1; Level 1 is also referred to as "Mirroring". A RAID 1 array is very simple, two or more disks act as one logical disk, and data is mirrored between the disks. If you have an array consisting of two 36 GB disks, you will end up with a logical disk of...
