It seems entirely possible to "store" data in ways that are not dependent on things that are traditionally said to have weight. For example, you could stream data as electromagnetism, making how much it weights completely dependent on your definition of "weight". Imagine streaming the entire internet into outer space with a pulsating laser. In transit, it would weigh very near nothing (IANAP, but it's weight would probably be the mass-equivalent of the total energy of the photons), but could still be read at a later time.
