What happens to a database if the flashback location goes offline ?

I am trying to move away from conventional cold backups only and thus have stepped into the realms of trying to use the flashback and archive logging to decrease the gap between now and the last backup that is restorable from tape.

Unfortunately the only volumes I have available to plant the flashback db, that is not on the same disks as the DB itself, are raid 0 arrays.

So my question, what would happen to the running DB should the flashback area go offline (disk failure). Aka, can I risk putting it on a raid 0 or should I get more disks to add another raid 1(or 10) array to it.
