Longevity has always been an issue.
(and we already know that 8" floppies outlast 3.5")

Does anybody here have experience with "M-Disc"?

It is available up to 100GB BDXL!
Drives start at less than $100; media is prices vary - the 100GB starts at 
about $20 each, but the low capacity versions are bordering on 

The longevity claims are all extrapolations - turns out that nobody has 
ever ACTUALLY stored one for more than 30 years.   If/when I can get a 
ride, I'd be glad to take one back to the sixties, to get a half-century
