It continues to amaze me how indestructible SDCards are.
The SDCard that was in another sub, properly constructed from titanium not carbon. The sub housed a camera, no humans.

It's a solid piece of silicon encased in epoxy, so there's nothing really to get crushed. Contrast this to something like a cellphone that's made of hundreds of separate parts and has void space that will get crushed.
Why isn't a cellphone filled with epoxy?
That would be a problem for the mic and speaker, and has relatively few use cases.

How would you do screen replacement? That is a common repair since people drop their phones and currently you can get your phone repaired by some teenager in a booth at the mall. If you fill the phone with epoxy, how are you detaching the screen, and getting a new ribbon cable through the epoxy?

Heat and wear are the greatest dangers to flash memory, and this was found in a cold dark place, with presumably plenty of life remaining.

I'm sure there are some companies who want to do that, as long as they can convince people it's better for security or something.

It's just not necessary, while having reliability problems of its own.

There's only 3 manufacturers of SD cards in any volume, you can compare the branding and font choices and see who's it is.
