Edit: I replaced it with a book
I’m specifically referring to microSD cards here, but I’m too lazy to type that every time and I doubt many people will think of full-sized ones anyway.
I got two 256GB SD cards (Samsung pro plus something) for Christmas, but I can’t think of a good use for the second one.
I have a Raspberry Pi, currently with a 32 GB SD card, where I’m gonna put the first one.
My phone has 128 GB of storage, which is already enough for me.
I’m considering putting it in my Nintendo Switch, but it already has a 64GB SD card, which is enough for the 2 non-physical games we have.
I plan on getting a Steam Deck once I can afford it, but that already has a lot of storage.
I don’t have a camera or drone or similar.
Selling is not an option.
A refund is technically an option, but I’d rather find a use for it.
If it’s a higher speed than the 64GB one in your Switch, it could make sense to replace it with the new 256GB one for slightly faster game loading times.
If you had a rooted Android I would have suggested using the SD card for primary photo storage, and app backups/“timeshift-like” restore. I use mine for both, as well as offline maps, app data, and some LLaMA models before the AI LLM novelty wore off
