Common RAID Types
- RAID 0: Striped disks that provide improved performance but no fault tolerance. If any disk fails it is possible all disks in the array will also fail.
- RAID 1: Mirrored disks that provide protection from disk errors or failures. The array continues to function as long as at least one drive is operational.
- RAID 2: Offers redundancy by synchronizing in very small stripes.
- RAID 3: Striped set of disks with dedicated parity. Improves performance and fault tolerance by using a dedicated parity disk. Allows for continued operation even during the lose of the parity drive.
- RAID 5: Striped set of disks with rotating parity. Has the same fault tolerance ability as RAID 3. Improves a lot performance on random write in comparison to RAID 3. Allows for continued operation even during the lose of the parity drive.
