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+2 30.8%
striped raidz + HS 4x(2 data, 1 parity), 1 spare 61.5% (8) 1+1+1 25%
mirrored raid2z + HS 2x(4 data, 2 parity), 1 spare 30.8% (4) 6+2 46.2%
mirrored raidz + HS 2x(5 data, 1 parity), 1 spare 38.5% (5) 6 + 1 46.2%
