Redundant Array of Independent Disks (RAID)
A collection of disk drives used for fault tolerance and improved performance, and is typically found in large network systems
RAID 0
- Striping
- File blocks are split between two or more physical drives
- High performance
- No redundancy
RAID 1
- Mirroring
- File blocks are duplicated between two or more physical drives
- High disk utilization
- High redundancy
RAID 5
- Striping with parity
- File blocks are striped
- Efficient use of disk space
- High redundancy
RAID 6
- Striping with 2x parity
- Add another parity block
- Could lose two drives and data would continue to be available
- Requires another drive
RAID 10 (RAID 1+0)
- The speed of striping and the redundancy of mirroring
- Needs at least 4 drives
