RAID Calculator
Calculate storage capacity, performance, and redundancy for different RAID configurations
RAID (Redundant Array of Independent Disks) is a data storage technology that combines multiple disk drives into a logical unit for the purposes of data redundancy, performance improvement, or both.
RAID Configuration
About RAID Levels
RAID 0: Striping without redundancy. Highest performance but no fault tolerance.
RAID 1: Mirroring. Excellent read performance and fault tolerance but 50% storage efficiency.
RAID 5: Striping with distributed parity. Good balance of performance, capacity, and fault tolerance.
RAID 6: Like RAID 5 but with double parity. Can withstand two disk failures.
RAID 10: Combines mirroring and striping. Excellent performance and fault tolerance.

RAID Level Comparison
| RAID Level | Minimum Disks | Fault Tolerance | Read Performance | Write Performance | Storage Efficiency |
|---|---|---|---|---|---|
| RAID 0 | 2 | None | Excellent | Excellent | 100% |
| RAID 1 | 2 | 1 disk | Excellent | Good | 50% |
| RAID 5 | 3 | 1 disk | Excellent | Good | 67-94% |
| RAID 6 | 4 | 2 disks | Excellent | Good | 50-88% |
| RAID 10 | 4 | 1 disk per mirror | Excellent | Good | 50% |
Note: These calculations are estimates. Actual performance and capacity may vary based on hardware implementation, controller, and workload patterns.
