Any Nintendo Switch 2 storage discount looks good right now, so half off a Samsung microSD card is a surprising discount we won't say no to
Samsung didn't hear about the price increases
Despite memory and storage — and therefore gadgets themselves — getting a lot more expensive of late, Samsung apparently missed the memo, because a Prime Day storage discount sees a Switch 2-compatible microSD card lose half of its value.
Righty now, you can pick up a 256GB storage Samsung P9 micrSD Express card for $40 at Amazon, which is a saving of exactly 50%. There's no discount on the 512GB model, which currently sells for an eye-watering $200 (yes, two hundred), and storage discounts over Prime Day are pretty modest all around.
Samsung P9 microSD card 256GB | $79.99 $39.99 at Amazon
Save $34 - This 256GB Switch 2-compatible storage card has technically gone cheaper in the past, but doesn't see as frequent discounts any more. It's one of the few serious reductions on microSD cards this Prime Day.

Amazon has several other Switch 2 microSD card deals, but I'm not finding any others that cost less than Samsung, are from a reputable company, and work on the Switch 2. So it's an ideal choice to bump up your Switch 2 storage.
Should you buy the Samsung P9 microSD card?
With transfer speeds of up to 800MB/s, this Samsung microSD card is fast enough to be sufficient for Nintendo Switch 2 gaming. Many other similar cards on Amazon, including the few other discounted ones, have much slower speeds.
This means they're not ideal for gaming with. However if you just want some extra space for your smartphone, tablet or for non-gaming purposes on your Switch, you might be able to opt for slower speeds.
What about the size? Games on the Nintendo Switch 2 typically don't take up the space space as their console or PC counterpart, so 256GB isn't as small as it initially might seem. Mario Kart World, for example, was 23.4GB, while Sonic X Shadow Generations is 24GB and Pokémon Legends: Z-A is just 7.7GB. So if you're only planning to play Switch 2 games like these, 256GB is more than enough.
Some AAA games ported to Switch 2 take up more space: Assassin's Creed Shadows needs over 62GB while Cyberpunk 2077 needs 60GB and Indiana Jones and the Great Circle needs 56GB. So if you plan to download a few of these games, you might find 256GB a little tight.
Saying that, you'll be hard-pressed to find any reasonable prices on 512GB memory cards, so I'd really recommend sticking to smaller sizes. It's cheaper to buy two 256GB cards than one 512GB right now!
