How many SD cards do you have?

Just got my Steam Deck a couple weeks ago, so as of right now I just have a 1TB card for random games, and another for ROMS/EmuDeck. Then I got a case that came with a little holder for SD cards, as well as a bunch of labels that say "RPG", "SIM", etc., and I started pondering the possibility of having so much more of my library available at just the swap of a card.

Long story short, I'm now staring at a dozen SD cards in my Amazon cart and wondering if this is a slippery slope.
