RAID is an acronym for Redundant Array of Independent Disks
RAID-0 – Striping (disk space is striped across two or more disks)
RAID-1 – Mirroring (data from one plex is duplicated on another plex to provide redundancy)
RAID-5 – Parity (RAID-5 is a striped layout that also includes the calculation of parity information, and the striping of that parity information across the disks. If a disk fails, the parity is used to reconstruct the missing data.)
RAID-0+1 – Mirror-stripe (disks are first striped (or plain concat) and then mirrored)
RAID-1+0 – Stripe-mirror (disks are first mirrored and then striped (or plain concat))
