This is not hardware RAID at all, it's just cheap software RAID on a chip. The 
RAID logic is passed onto a proprietary driver that runs off you CPU. Why 
anyone would trust their data to a cheap proprietary piece of kit is beyond 
me.

The answer to what I wrote above is Linux Software RAID, as Gabriel's HOWTO 
explains. It's tried and proven, has good recovery tools, and doesn't keep 
your data dependent upon a proprietary hardware/driver combination.
