Hurry, Prime Day's cheap memory cards are perfect for Nintendo Switch and Steam Deck
These Prime Day memory card deals won't be around for long
One of the great Amazon Prime Day traditions is big memory card price cuts, and this year is no different. Whether you own a Nintendo Switch, Steam Deck, or mirrorless camera, we've picked out all of the best Prime Day memory card bargains – but it's worth getting a move on, as these will likely disappear tomorrow.
For Switch and Steam Deck owners, a generous microSD card is a great upgrade to their portable gaming machines. On the Switch, it gives a healthy boost to the somewhat measly internal storage, while on the Steam Deck it remains a better (and cheaper) option than installing an SSD drive.
We've scoured the virtual shelves of Amazon's Prime Day deals to pick out the best options for both below. Not all the capacity options of cards below have received the same level of Prime Day love, so we've highlighted the ones we think offer the best savings based on historical pricing. But you can of course find larger (or smaller) versions by clicking through to the listing.
To make sure photographers don't feel left out, we've also picked out some choice SD card deals for mirrorless cameras. This year, Lexar's cards are offering particularly good value, but as always some SanDisk cards have also dropped down to their lowest-ever prices. Happy memory card shopping - we're certainly planning to pick up a few before the Prime Day deals end later today.

Nintendo Switch cards (US)
SanDisk Ultra 512GB SD card: $99.99 $46.99 at Amazon
Save $53 - Save over 50% on this 512GB SD card. The Nintendo Switch doesn't have a huge amount of internal memory, so you'll need to plug in an SD card if you want to download heaps of games to take on the go. You can't go far wrong with this one – 512GB will likely take your whole gaming library, and SanDisk is a reliable brand.
SanDisk microSDXC UHS-1 card (512GB): $129.99 $69.34 at Amazon
Save $60 - SanDisk's licensed Switch cards have some charming designs, including this Animal Crossing-themed number. Unlike the other capacities in this series, this top-capacity 512GB card has been given a big Prime Day discount – it's never been cheaper than this and should swallow your whole game library.
Steam Deck cards (US)

SanDisk 128GB Extreme Pro SDXC UHS-I Card $44.99 $25.99 at Amazon
Save $19 – Not all capacities of this card are Prime Day bargains, but this one is – it's never been cheaper than this. It served up very solid 90MB/s shooting speeds and 170MB/s transfer speeds. That makes it a fine option for continuous shooting and 4K video, while its tough build (and lifetime warranty) make a it a trustworthy workhorse.
Lexar Professional 2000x UHS-II (64GB) $94.99 $56.99 at Amazon
Save $38 – There's great value to be found in Lexar's excellent Professional series cards during Prime Day this year.
