What's the best setup for 13 drives? I don't need high performance (this will be mostly for archiving media), but very much do not want to lose my data. The drives are 18TB, and ZFS will be used exclusively.
| Name | Setup | Availability | Tolerance | Max Rebuild | Perf |
|---|---|---|---|---|---|
| raid3z | 10 data, 3 parity | 76.9% (10) | 3 | 100% | |
| raid3z + HS | 9 data, 3 parity, 1 spare | 69.2% (9) | 3 | 92.3% | |
| raid2z + HS | 10 data, 2 parity, 1 spare | 76.9% (10) | 2 | 76.9% | |
| striped raid2z + HS | 2x(4 data, 2 parity), 1 spare | 61.5% (8) | 2 sets of 2 | 30.8% | |
| striped raidz + HS | 4x(2 data, 1 parity), 1 spare | 61.5% (8) | 3 sets of 1 | 25% | |
| mirrored raid2z + HS | 2x(4 data, 2 parity), 1 spare | 30.8% (4) | 1 set of 6 and 1 set of 2 | 46.2% |
