Walmart is currently offering the lowest prices on Nintendo Switch 2 MicroSD Express memory cards, with discounts on both 512GB and 256GB Onn-branded models. The deal is timely given a wave of recent Switch 2 console purchases and ongoing storage pressures, as several major games now demand huge amounts of space. Switch 2 owners cannot reuse standard MicroSD cards from the original Switch, since the new console requires the faster MicroSD Express format, making a compatible upgrade a near-inevitable purchase for many players.

The Onn 512GB Micro SDXC Express Card is priced at $84.77 with free shipping, while the 256GB version, also back in stock, costs $46.77. Both offer read and write speeds of up to 800MB/s and 600MB/s respectively, and are confirmed compatible with the Switch 2, which has 256GB of built-in storage. Storage-hungry titles such as Final Fantasy VII Remake Intergrade (90-100GB), Split Fiction (70GB), Cyberpunk 2077 (60GB) and Hyrule Warriors: Age of Imprisonment (44GB) mean a handful of downloads can fill the console's onboard capacity, and the 512GB card would roughly triple total available storage.
