Raw is often quoted as being better, but if you know a lot about tuning
filesystems, and unix cache buffers you can make the performance the
same.
Data Integrity:
Doesn't really make a difference, except you can use standard unix tools
like tar, cpio to backup file systems. You only get logical disk copy
(if available) and oracle backup for raw.
Recovery:
Doesn't really make any difference, for good recovery make sure you run
in ARCHIVELOGMODE with automatic archiving and keep you log files for
more than 2 dumo cycles (i.e. 2 -3 days if you dump once a day).
Maintenance:
I like file systems. this is a bit woolly but "You can see them more
easily"
