The Nintendo Switch 2 features backward compatibility with many original Switch games, providing a bridge for early adopters until more exclusive titles are released. The console offers 256GB of internal storage, which may not accommodate an entire digital game library. For additional storage, Samsung’s 512GB P9 microSD Express card is currently available for $94.99, reflecting a $5 discount. A 256GB variant is also sold at its standard price of $54.99.
While the current discount may appear modest, the P9 is priced roughly $20 lower than many comparable 512GB microSD Express cards, with the exception of an Onn card available at Walmart for approximately $85, though it often runs out of stock. The Nintendo Switch 2 is among the first mainstream devices utilizing microSD Express cards, known for their high sequential read speeds, reaching up to 800 MB/s. However, these speeds are only fully realized in devices that support microSD Express slots.
The capacity of the 512GB card can vary based on the size of the games stored. For instance, “Hyrule Warriors: Age of Imprisonment” requires 43.4GB of space, while “Silksong” demands only 4.1GB. Some larger titles, such as the Switch 2 version of “Final Fantasy VII Remake Intergrade,” necessitate a download size of 93GB. Consequently, a combined capacity of 768GB may be useful for gamers with extensive libraries.
Additionally, physical game collectors might find a microSD Express card essential, as many games are now released on game-key cards—requiring downloads to the internal storage despite the use of a physical cartridge to authenticate ownership. Furthermore, numerous indie games may only be available digitally or later in cartridge form. Thus, having extra storage space could help avoid the challenge of selecting which games to bring on trips.
