5.2.2
RAID 1: Mirroring
RAID level 1, mirroring, each drive stores identical data. RAID 1 provides very high data
reliability and improved performance for read-intensive applications, but this level has a high
capacity cost because it retains a full copy of your data on each drive in the mirror set.
5.2.3
RAID 5: Striping Disks with Distributed Parity
By distributing the parity information across all drives in a set, RAID level 5 achieves high
reliability and data availability, which allows one of the array member disk to have failure and
keeps the storage working. Disk failure has a moderate impact on the total transfer rate.
5.2.4
RAID 6: Independent Data Disks with Two Independent Parity
Schemes
RAID level 6 extends RAID level 5 by adding an additional parity block; thus it uses block-level
striping with two parity blocks distributed across all member disks. RAID 6 allows two of the
array member disks to have failures at the same time and keeps the storage working.
