What would digtal storage look like in freedom units?

An imperial unit (let's remember we got this from the Brits who now say they're metric... but are they?) is generally based on something in day-to-day life so they're relevant. They would have probably been named in the late 40's or early 50's. So I suspect the they'd be based on ways data was transmitted then.

• 4 taps (like on a telegraph) = 1 character
  • so 1 tap is 2 bits
• 1 sheet (like paper) = 13,000 characters
  • so 1 sheet = 52,000 taps = 104,000 bits
• ... etc
• 1 bankbox = 500 sheets = 26 million taps = 52 million bits

edit: fixed my maths
