Capacity and Practicality are the major difference. If you do ignore those though, vinyl is a much better long-term data storage solution than CD.

A quick internet search suggest that a regular 12" record should have a capacity of around ~10-20MB. That is just enough to store one regular JPG photo.

There seem to be print shops that will press records for you at the cost of around ~$100/copy (minimum run 100 copies).

So to back up my ~1,000-ish photos per year I just need a climate controlled warehouse and 99 friend-with-warehouses to distribute backups too!

I have vinyl records going back to the 1920s, and they're just fine.
