These brilliant posters spell out the number of floppies needed to load iTunes, Firefox and even Photoshop. I'm so glad we only have to insert one disc instead of 358 floppies for Photoshop CS4 these days. [Behance via Photojojo]
A single 3.5 inch floppy holds around 1.4MB. A single CD is around 700MB, which is about 500 floppies. A DVD is 4.7GB which ends up being around 3,350 floppies. A single Blu Ray disc at 25GB holds the equivalent of roughly 17,850 floppy discs.
I think I just blew my own mind.
