In a hundred years the media might survive but the ability to access that media might not.Right @TJ Hooker , so it isn't really being all that helpful telling me that you failed to locate the same information and assumed those exact links were the ones I was referring to while looking at several dozen different SD card store page's worth of information on that day.
Just here to learn the solution to longterm storage, which type of storage is most secure, pros and cons of each and for the most part learn this by stating what I understand so far. These aren't claims as you say, I am more looking for confirmation of a lot of such details and may be writing them in a manner that can be seen that way (apologies).
If SD cards are not that solution, that's perfectly fine, but please try suggesting something that I can do to actually keep data over decades (or more) as I requested.
Okay so they're very similar technology to SSDs and SSDs are also generally magnetproof/waterproof to an extent. Is that right? The gravity point of dropping SSD vs SD card though does still kinda stand strong. But at the cost of all that speed.
STILL! Speed is semi-irrelevant for this bank-vault type secure data storage that I'm seeking. Is there really nothing to be done for archival storage besides cloning the data to other devices on a somewhat regular basis?
What if I wanted to seal some humanity-crucial data in a 3-inch thick steel chest for 100+ years with an "Open in 2119" tag on it? How can I ensure the survival of the data/devices of that buried chest?
Almost seems vacuum sealed paper would be a safer alternative.
