That's clear to me.
These "hardware" raid controllers are not very reliable because they are 
indeed not real hardware raid controllers, but software based.
Maybe for desktop usage it's ok/ good enough?
It is better to use the operating systems raid capability linke gmirror instead.

Of course real hardware raid controllers with cache and battery backed are a 
different thing and very reliable.
