Hi! Definitely do NOT put your rollback segment tablespaces to non-raid disks, if you don't want your database to be down in case of media failure. Also, if your system has to be highly available, I wouldn't put anything except maybe multiplexed online logs, archive logs and possibly some backups and such stuff on non-raid. Even temp shouldn't be on non-redundant disk if you don't want to lose your on disk sorting ability in case of media failure..
