Preppers
A place for people who like to be prepared for realistic disasters both human created and naturally occurring!
We expect there to be thematic overlaps with outdoor, survival, general preparedness, self-sufficient living and resilience... also gear talk is welcomed wholeheartedly.

For long term storage, I would recommend using "M-DISC". I ran into this post on "all" and it has some overlaps with one of my areas of interest, data hoarding.
Most storage media (HDD, SSD, USB, MicroSD) have a lifespan rating of about 10 years. This means that after 10 years you should not trust these media to keep your data intact. BluRay is a bit better at ~20 years.
Like I mentioned, M-DISC would be your best best for long term storage. They are rated to last for 1300 years or so (which is obviously still untested haha). You can buy 250 GB of M-DISC storage for $40/€40.
I would argue, that swapping the medium, as well as swapping/updating the data (ID, licenses) can be part of a regular schedule. TEOTWAWKI and long term storage is a different topic.
