it sounds like a better option, for now i mean less trouble on swapping sd xD or am wrong ?No so far, some people says what don't do it, but may be old lady stories, because some years ago the file based EmuMMC was slowest and prone to corruption but since several versions of Atmosphère all the bugs are corrected and now there is no difference between Raw Partition and File based.
as today is more a manner of taste.
