That graph is for fat32, which is really really dumb in the way it does allocations. Reiserfs does "tail packing," which allows us to pack data in with metadata, eliminating most of the waste that you're afraid of. In fact, by choosing a smaller block size, you actually waste *more* space since more metadata is needed to describe it, and each of those metadata blocks needs a portion of it for headers, etc. - -Jeff - -- Jeff Mahoney SUSE Labs -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iEYEARECAAYFAkl3dqQACgkQLPWxlyuTD7KOdwCgoPs3UxgdETHZ5p4D/czIqV1I Jr4AoIA6QFySoLr5OaRsHawTbTD4GDzd =HRr2 -----END PGP SIGNATURE----- -- To unsubscribe from this list: send the line "unsubscribe reiserfs-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
