I'm just thinking... I wonder if it would be possible to somehow replicate the
OS on both the SSD and the hard drive, such that you could just change the boot
device in the bios to point to one or the other.  Which wouldn't exactly be a
raid (with the overhead that entails) but just a change of boot device as
required.
