Redundancy through parity. Minimum of three discs. Most common
5
Q
RAID 6
A
Striping with dual parity
6
Q
RAID 10
A
Mirroring and striping
7
Q
Failure Resistant
A
Protection against the loss of erased data (RAID 1/RAID 5)
8
Q
Fault Tolerant
A
Raid can function even when a component fails (RAID 1/RAID 5/RAID 6)
9
