Seagate has introduced the Exos M series, a range of enterprise-grade mechanical hard drives available in 30TB and 32TB capacities. The two models, the 30TB CMR ST30000NM004K and the 32TB SMR ST32000NM003K, each offer a minimum of 3TB per disk and use a standard 3.
Is RAID2 ever the right choice? Honestly, I don’t touch anything outside of 0, 1, 5, 6, and 10.
Edit: missed the z, my bad. Raidz2 is fine.
raidz2 is analogous to RAID 6. It’s just the ZFS term for double parity redundancy.
