When your motherboard dies you then have no data available to use
unless you have another motherboard with the exact same fake raid
chip-set. OTOH with software raid you can hook your discs up to any
motherboard and it'll all start fine because it's not tied to the
hardware.
We had a boarder who used fake-raid in the fashion you mention and
was bitten badly by a raid chip failure. No spare motherboard, no
backups, everything gone.
