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.
This is an interesting idea, especially with using a small cheap SSD to boost boot speed.
Don't see any reason why it cannot be achieved simply by doing the same thing of using mdraid RAID 1 with partitions and using the write-mostly on the HDD partitions.
