Actually Oracle has features that only work with raw/io, e.g. parallel
server.
Once you know how to handle the raw devs they are a lot more convenient
than flat files. If you have a 100 Gb + DB raw dev is the only way to go.

    I've  seen  a  800+  GB  Oracle database using filesystem and
    performing well.  But  that  needs  a  GOOD  filesystem,  not
    something like ext2.
