A dedicated hardware RAID controller, like you are mentioning here, is definitely where a true RAID array has its power. My examples, and where I have continually seen RAID arrays fail, has been using onboard RAID controllers and software RAID. The complaint I hear from customers that are dead set on using RAID, though, is "I don't want to spend an extra $400 for a card that does the same thing as what's included on the motherboard!" But, that $400 makes a huge difference in the actual performance and reliability of that array!
Anymore, if you're doing a file server system, just spend the extra money and get a decent RAID controller card.
Hear, hear... !!
Actually, I think I only paid about $150 + shipping for the 3ware card that I have...
Far better than any Promise controller...
