Let me clarify: In my experience software RAID is more stable than /on board/ hardware RAID. An expensive RAID controller with batter backup will, of course, give you better performance and reliability than software RAID. On-board controllers like you find in consumer desktops and even many server boards are pretty much all low quality. If you find a server board with good on-board RAID great, and you are probably spending as much for it as you would for a dedicated card.
