http://www.prepressure.com/techno/raid.htm for an explanation of raid types.
Personally, after using raid (mirror) on a motherboard controler & then
suffering problems, which were acknowledged by Asus tech who said that they
had thought the bios upgrade had cured the problem, I purchased a raid card
with a retail price of some $500 (Ebay, still sealed with the warranty for,
much less) This is a true hardware raid card with its own bios.
I'm sure motherboard raid controllers have improved since then, however they
still rely on your cpu for proccessing.
Whichever way you go, and even if using mobo raid that has hot swap ability
you should still have a data backup procedure in place.
As my data is critical to me I use mirror raid with inbuilt hotswap hd that
automatically rebuilds on hd failure, I then have an offsite backup, and
both onsite Imaging & backup using seperate media and seperate backup apps
