A History of Storage, From Punch Cards To Blu-ray 160
notthatwillsmith writes "Maximum PC just posted a comprehensive visual retrospective about data storage, starting with the once state of the art punch card and moving through the popular formats of yesteryear, including everything from magtape to Blu-ray discs. It's amazing how much data you could pack on a few hundred feet of half-inch magnetic tape!"

A good metric in general, but in this case the first page would consist of a zero, a decimal point, and lots of other zeros followed eventually by a significant digit.

That's 10. Ignore the previous notches. Some young whippersnappers thought it would be funny to do "subtractive" forms whereby IV would be "four". Oooo. I'm so impressed. Not. GET OFF MY LAWN.
Oh, and they forgot about magnetic drums. :-P

Yup, the line across the top trick saved me once or twice in High School. I moved from a school with PDPs and TTYs for the students to one with an 029 keypunch and daily trips to the computer building. Talk about a downgrade... But you quickly learn to protect your card stack.
On the last day of our Senior year, the computer geeks brought out the carefully-collected chad from the keypunch - and rained it down the 5-story main stairwells. I'll bet there's chad in there to this day...

The article fails to include the Library of Congress, to which all other storage mediums should be compared...
You should see how much information there is at the Congress of Libraries!

Calculate the bandwidth of a guy walking - even slowly - across a computer room floor with a reel of mag tape under his arm.
