Let there be one million 78rpm discs of classical music.
There will be a mix of 10" and 12" discs.
Each disc has two sides.
Each disc is 8 minutes in duration.
mp3 compression means 1 minute = 1 MegaByte
Total CLASSICAL music = 8 × 10^6 × 10^6 Bytes = 8 TeraBytes

Let there be a 4 TeraByte pocket drive.
Therefore the world's CLASSICAL music on 78s fills up 2 4TB pocket drives. 
This will put you back $100-150.

Try Blu-Ray. A 25GB disc costs about 25¢. $0.25/25E12.
8e12/25e9= 0.32e3, or  320 blu-ray discs. At a cost of $0.25, this is $80.

This is cheaper than using 2 4TB drives, or $100-150.

How long will it take to copy 8TB from one pocket drive to another is 
about a day. I have a Dell XPS (Windows 10), hardly top of the line.

My four Cs:
1. cataloging (ARSC standards)
2. collecting (cheap for the first 900,000)
3. converting (to .mp3 files)
4. copyright  (negotiations or changes in the law)

Any thoughts?
