6.2.1 RAID 0: Striping
RAID level 0, striping only, is the fastest and most efficient array type, but offer no
fault-tolerance. Any drive failure will destroy the data in the array.
6.2.2 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.
6.2.3 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.
