I have no idea about the difference in performance while
recording, but I don't see why you'd have to go thru the
file 24 times -- you should be able to write a "separation"
program to post-process the single capture-file into 12-24
individual files. I mean, even at a few GB doesn't take up
much room on a 100 GB HD which I've seen offered for under
$300 a few days ago.
