Must likely yes.  Using onboard proprietary software raid is just asking
for trouble.

Some boards MIGHT use the same on disk format if they use the same
controller chip and mostly the same firmware version.

I also would rather use something with known good performance for
software raid rather than something proprietary that ties me to a
specific board and someone's (usually) secret implementation.
