This certainly isn't the correct solution, but since the data file locations are chosen round-robin, one could use multiple data file directories per drive in the desired ratio and it would come out approximately correct if I'm thinking about it right. e.g. with 300gb and 500gb drive, 3 directories on the 1st and 5 directories on the second could be listed.
