But - be aware of compressed filesystems:
If you look with "ls" to the filesize, they don't grow, they are allocated
by creation. A compressed filesystem like jffs2 compresses such an empty
.rrd file to about 5%.
Over time, when you update the rrd-file you add information, so it can be
less compressed, after some years it can only be compressed to 50% - so the
space used on the medium grows.
