So I’m planning on doing RAIDZ2 or RAIDZ3 with 6 4TB drives. I already had the 4 WD drives and this black friday there was a sale on the seagate drives. Will this cause a problem when creating the vdev?
firmware bugs are like 0-days for your storage. my ideal nas has no two of the same drive. the newer builds of ZFS (i think as of freebsd 12) handle heterogeneous pools really well
