Nintendo confirms Switch actually supports SDXC memory cards up to 2TB
During yesterday’s Treehouse Live stream, Nintendo said that Switch will support microSDXC cards that hold up to 256 GB of data. That actually was incorrect. Nintendo now notes in an official statement that “Switch is compatible with the SDXC standard, which supports up to 2TB.”
2TB cards are not actually out on the market. However, Switch will support them when they are.
It’s worth noting that even 1TB SDXC cards are still awhile for most consumers, as they were just announced last September. 512GB is currently the largest available SDXC card.
