Back of the envelope maths. A floppy disk could attain typically 50 KB/s on a good day ignoring head seeks. 16 GBs of game data would thus take at least 320,000 seconds, or around 90 hours to load, But that's assuming a floppy disk capable of storing 16 GB. If spread across multiple disks, you'd need 11,000 floppy disks. In reality, you'd spend 4 days without sleep swapping 11,000 disks to get the game to run. Loading the next level might take a day and 3,000 floppies.Also the floppy disk was just a figure of speech related to even lower data transfers...
