I love the fact the hard disk manufacturers tend to list their disk drive capacity in powers of 10 instead of powers of 2 (likely because the round-down error makes their drives seem bigger).

In that case. Why not try to adapt an Atari 1050 disk drive? It can store 1 Terabyte* of data on a single sided double density floppy disk!

*I choose to define a Terabyte as 130,048 bytes.
