The officially licensed Samsung microSD Express Card remains the most popular option for Nintendo Switch 2 players who decide to upgrade their storage. The Super Mario-themed card is only available in 256GB, but Switch 2 owners will soon be able to get a Samsung card with 512GB of storage. The Samsung 512GB P9 microSD Express Card is available to preorder at Amazon for $95 (was $100) ahead of its November 4 release. You need to click the coupon box on the store page to get the $5 discount.
This is Samsung’s first microSD Express that isn’t licensed by Nintendo, but it has similar specs. Samsung is also launching a 256GB edition for $55, which is five bucks lower than the official card. The P9 has the lowest MSRP of any 256GB and 512GB microSD Express Cards on Amazon, but both editions cost about $10 more than Walmart’s Onn brand. The Onn 512GB microSD Express is currently going for $84.77, while the 256GB model is only $46.77.
Other popular and high-performing options include the SanDisk 512GB microSD Express for $120 and the Lexar 1TB Play Pro for $200 (was $220). Lexar is the only major storage brand offering microSD Express in 1TB.
