I wanted to jump in to suggest you reconsider motherboard driven fakeraid. The mainboard becomes a single point of failure, and replacing it or migrating the array can be problematic, especially with different chipset revisions or BIOS versions.
I recommend you set up a mdadm array. Drivers are in the kernel, documentation is profuse, and management is fairly simple once you get the hang of it. The graphical installer can even do it for you. Use the array for /home and possibly /etc and /var, and keep your root filesystem separate from your important data.
There is a downside to using mdadm over fake raid and that is that you can hit a bottleneck with the PCI bus as the data needs to be sent to each disk drive that needs a copy of the data (or parity info) instead of just once to the controller. Typically this will be twice as much data.
That said, I use mdadm. I have done such things as drop one side of my raid 1 mirrors, repartition that drive, set up new mirrors with encrypted file systems, and copy over file system data, repartion the other disk, add those partitions to the new mirrors.
doesn't fake raid do the same thing? If there isn't an intelligent controller, the same type of data still has to travel through the exact same bus. Neither have write-back cache that would actually improve peformance.
Additionally, fakeraid requires proprietary kernel modules, dies with the motherboard and typically is slower performance than mdadm.

Do I need to set any corn jobs to monitor the raid? This is recommended in most of the guides I read. If so, any suggestions why and how to do this?
