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.
