It's not much, but relatively speaking it's much more.

I'd say up to a couple of hundred is much more than 40. Not a full decimal order of magnitude, but even without compression the 170KB on one side is up to 4½×.

It could still be much more depending on how much data fits on a single side of a 1541 floppy.
