Chap 5: RAID Not RAID - Spanning or JBOD

RAID 0 – Striping

RAID 1 – Mirroring

RAID 5 – Striping with parity (3 Disks minimum)

RAID 10 (1+0) – Striping and Mirroring (4 Disk minimum)

RAID takes special hardware or software. Windows has RAID support in software, but it would be better to use RAID hardware.
