It depends. If you are running without an LVM raw files will usually give you better performance. When running with an LVM results appear to be mixed.

Unless you are running Oracle Parallel Server you need not use raw devices.

Based on your comment it would appear that Oracle is "operating system-friendly" when compared to Sybase since Oracle runs quite well with cooked files.
