The fastest Steam Deck memory card we've tested is $29 for 512GB at Best Buy in the US
Samsung's Pro Plus Micro SD card is our top memory card recommendation for PC gaming handhelds like the Steam Deck, ROG Ally and Legion Go, and today you can pick up the 512GB version for just $29 at Best Buy. That's a pretty steep reduction from its previous price of $48 and even beats the best Black Friday price we saw this year of $31.
Note: the photo above shows the 256GB model we tested, but I can confirm this price is for the 512GB size.
