Don't use fake raid.

If you have to then skip it and treat them like 2 SATA drives.  Use md
tools in Linux to RAID1 the drives.

Make sure you install grub on *both* drives.  That way if one goes bad
it will still boot

Also don't place swap on one drive but on a md device.  If a device goes
bad and you are swapping on that drive you'll box will die.

These are just a few things I learned when dealing with fakeraid and md
tools.
