raidz2 is only advised against if your arrays are so small that you don't care about the price of storage.

If you want more IOPS, add more raidz2 (raid6) stripes to the pool. In practice, spinning rust is the new tape. Trying to do random access under 1MB is just silly

I don't stress over rebuilds. 2 more disks failing during a rebuild is incredibly unlikely compared to everything else that might force me to restore a backup (software bugs, data center flooding, etc).
