There are too many simpler, faster, more resilient options considering rootfs at most isn't bigger than the average SSD: Two or three SSDs + n-way mirroring. RAID 10. Or RAID 1 + linear + XFS for deterministic workloads. Those three examples are simpler, more resilient, easier to configure and maintain, perform better, with faster rebuild times than RAID 6 which also has a high read-modify-write penalty. I left that part out.
