What data and settings...are you referring to?
I have employed several RAID controller cards in the past...each time the card is moved to a new motherboard/system, it must be installed. That results in the new system now having two BIOSes (one for the card, one for the system) to properly set up in the system BIOS.
I know of no settings/data that are stored on the RAID controller, other than the BIOS. All data is stored on employed hard drives.
It's been a few years since I even thought about using my controller cards, so my under standing may be clouded by lack of current situations.
