Hardware raid virtually always outperforms software raid in
performance and reliability. hardware raid is usually less flexible
however..
Operating systems does not notice the raid of a hardware raid. To the
operating systems the raid set just looks lie a normal hard drive.
Hardware raid operates outside the operating system, providing raided
harddrives for the operating systems to use.
Side note: some software raid systems also supports journaling which
is a completely different aspect of filesystem I/O not related to
raid.
