Is this really true (that about being fake and harder to recover)? I recently bought a new motherboard (ASUS M2N32-SLI Deluxe) and it comes with two onboard RAID controllers. Currently I have Vista installed with a controller setup to handle RAID 5 across three identical disks. I've been doing a lot of reading about this and it seems to be that I would need to use dmraid to configure my system to allow Linux to install. If it's harder to recover with this fake raid then what's the point?
The Nvidia Control Panel claims it can rebuild the array while Vista is running when a drive is down without messing things up, though it warned that it would take its time.

-"Simon Bridge" says it won't work at all... LQ forum: here
Some other forum posts I've read have links to comparisons for performance of hardware-based raid and software-based raid. ("Simon Bridge"'s post has such a link, above).
Basically I'm looking for a reliable way to prevent data from being lost if a disk fails. I don't really have enough cash for a RAID controller, and my needs are not that great for one at the moment.
I also read GRUB doesn't work when on an onboard RAID config...?
Does anyone recommend something? I'll reinstall everything if I have to, but I really want to at least
tri-boot my system with Vista on NTFS, Kubuntu on ext3 and Gentoo on reiserfs (to play with).
If it's too much of an issue i'd also be willing to go without the entire RAID setup, but if it will work without much trouble i'll keep it.
Thanks for any input!
