RAID Levels

RAID 0 (Striping)

Maximum performance and capacity, but no redundancy. Data is striped across all disks.

RAID 1 (Mirroring)

Complete data redundancy. All data is mirrored to a second disk. Requires even number of disks.

RAID 5 (Parity)

Good balance of performance and redundancy. Uses parity for data protection. Requires minimum 3 disks.

Quick Examples

RAID 5 with 4x4TB

  • Total capacity: 16 TB
  • Usable capacity: 12 TB
  • Redundancy: 1 disk

RAID 10 with 6x2TB

  • Total capacity: 12 TB
  • Usable capacity: 6 TB
  • Redundancy: 2 disks
