This is absolutely a good thing to do, but it doesn't make you safe - the disks running the database's redo logs are the ones that get hammered in a logging scenario (since the writes to the table and indexes are largely appending, and don't have to be written to disk to commit a transaction). These logs are usually global to the DB instance, so you can't easily (to my knowledge) separate them out. This being the case, they can significantly affect the performance of the rest of your system if too much logging starts happening.
