What can I do with a SD card? (lemmy.blahaj.zone)

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.

I would use the second one as a backup.

You could use one of these USB SDcard reader and script something that backups the content of the running/live SDcard to the second one on the USB stick. With dd or something you could have an always ready backup SDcard of the RasPi system.

That or using an old Android phone as a media center and putting the second SDcard in that.

Or using an old Android phone as a surveillance camera but that would be a bit overkill to have 256Gb.

Also if you have an early model of the Switch you could hack it to run pi... homebrews and in that case having a super large SDcard could be good.

Since they already have an extra card, why not. But buying one for the purpose might not be a good idea, see for example https://superuser.com/questions/1254904/using-an-sd-card-for-backup#1254907
