RAID = Redundant Array of Inexpensive Disks
| level | description |
| 0 | Striped disk array (mnemonic: "ZERO" fault tolerance) |
| 1 | Mirroring / duplexing / shadowing (mnemonic: "ONE" disk from two or more) |
| 5 | Independent data disks with distributed parity blocks |
| 0+1 | High data transfer performance |
| ...and just to be closer to complete... | |
| 2 | Hamming Code ECC |
| 3 | Parallel transfer with parity |
| 4 | Independent Data disks with shared parity disk |
| 6 | Independent Data disks with two independent parity schemes |
| 7 | Optimized Asynchrony for High I/O and Data Transfer Rates |
| 10 | Very High Reliability combined with High Performance |
| 53 | High I/O Rates and Data Transfer Performance (s/b RAID 0+3) |
