The motherboard raid has to be handled by a special software raid
driver inside linux. That means you are getting the exact same
performance as normal software raid but you are stuck with the
controler and highly specific metadata. Yu can't plug the disk into a
different controler and have it work there anymore.

Also the way the motherboard raid organises its data might be less
optimal than what normal software raid does. At a minimum it will be
less flexible. Linux software raid might be faster or slower but it is
tuneable to your needs. The motherboard raid will be static.

It is strongly recommended not to use the motherboard raids on any
board. It just has no advantage but drawbacks.
