RAID Level Selection Cheat Sheet

⚠️ Added for clarity (not directly from source)

- RAID 0 for speed only when data loss is acceptable.
- RAID 1 for high reliability and simple recovery.
- RAID 5 for balanced storage efficiency + fault tolerance.
- In answers, always mention both usable capacity and fault behavior.
- Visual explanation: Striping spreads workload, mirroring duplicates, parity reconstructs.
