Longevity of Recordable CDs, DVDs and Blu-rays

Hi:

The Government of Canada posted this thorough review of media longevity. I have thousands of optical discs but I never paid much attention to this topic. Lasted updated in 2020.

After a quick search I didn't find this on the forum, so posted it below. Apologies if it's redundant.

There are also two studies by the US National Institute of Standards and Technology on the subject.
