People don&#x27;t tend to use parity RAID primarily for uptime, they do it because it&#x27;s cheaper - HDD costs for a mirror&#x2F;striped-mirror implementation are always 1&#x2F;N, whereas with a RAID-6 it&#x27;s 1-(2&#x2F;N), or 1-(1&#x2F;N) for RAID-5.<p>In my experience, mirrored and&#x2F;or striped-mirror type RAID implementations are more reliable, performant, and easier to maintain than any variation of parity RAID. Even for a home setup, it&#x27;s just not worth my time.
