Probably raid 6 with spares as that allows for 2 simultaneous disk failures before you need to go to backups for recovery. And I think that having the spares will result in rebuilds happening as soon as a drive is marked as failed (but I haven't tested to see if that's how it actually works). Having the rebuilds start right away reduces the amount of time in degraded mode where you are fewer failures away from needing to go to backups. Generally if you REALLY care about this, you'll buy a hardware raid system of some sort. You might also get something with multiple controllers so that if you lose a controller you can still run in degraded mode. Being able to replace drives without having to shut down the system is also important. For a normal home user, I'd just go with raid 1.
