Was it this?
One interesting statistic about data sizes, IMO is the fact that the Bible is just about 5 MB of ASCII text uncompressed. It makes the amount of data you are talking about something that is more easy to relate to.
Belated thanks for tracking that photo down. I think the one I saw was actually street level going into the building but dimensions, era and capacity seem right.
While the Bible comparison is apt for storage, my comparison of a single MP3 or a single cell phone photo completely using up that 5MB was meant to be relative to anyone with a phone.
If we go out for a beach walk or a sunset I don’t think anything of taking 20 pictures or having 500 MP3s on my phone. Just saying. Thanks again for the pic.
