Caveat * Might need to adjust the DAT size limitations for smaller size sets to properly limit the dats from exceeding the value at all, rather than simply addressable initial space. Since the limits are now hardware defined, we can't simply address a mod at [Max bytes - 1] and not care if it goes over the limit.

Ex. A Fat32 drive will hard fail to write to bytes beyond 4GB, or a FAT16 or 32B OS will hard fail to write to bytes beyond 2GB.
