Continue with your redo logs, control files and
archive log files on raid0.
We have had two complete melt downs of raid5 storage.
The vendor said it could not happen, our storage folks
said it could not happen. It happened! When I was
consulting, I had a similar experience at a client
site.
The only files I will voluntarily put on raid5 are the
data and indexes. Everything else I want on raid0 or
0+1.
