I once threw my redo logs onto a RAID 5 array just for grins (while doing some preproduction testing before going live with a new database). The sysadmin and I saw a huge increase in disk activity, but that increase didn't translate into a negative impact on application performance. Who cares whether the poor disks are thrashing, so long as they are keeping up, right? Even so, we couldn't bring ourselves to leave the redo on RAID 5, so we moved it into RAID 0+1 before going live. My point here is that you just might find performance to be acceptable.
