The article explains that only microSD Express cards are compatible with the Nintendo Switch 2 due to its faster transfer speeds, with prices ranging from around $36 to over $200 for larger capacities. While the Switch 2 supports up to 2TB, 1TB cards are most common, and Walmart offers more affordable options. The console's built-in 256GB storage means additional microSD cards are not immediately necessary.
Western Digital has released a new line of WD Black C50 expansion cards for Xbox Series X/S, starting at $80 for a 500GB model, $10 less than Seagate's equivalent. These proprietary add-ons are required to add space for ready-to-play Xbox Series X/S games, which require solid-state drive cards as quick as the console's built-in SSD. While still costlier than NVMe SSDs for PlayStation 5, the price gap is now small enough that the storage format probably won't affect your choice of system.
