| 3 | Bit-interleaved striping with parity information (separate disk for parity) |
| 4 | Block-interleaved striping with parity information (separate disk for parity) |
| 5 | Block-interleaved striping with distributed parity information |
| 6 | Block-interleaved striping with two independent distributed parity schemes |
| 7 | Block-interleaved striping with asynchronous ... |
