1TB microSDXC UHS-I card with up to 100MB/s read and 90MB/s write speeds, officially licensed for Nintendo Switch
The SanDisk SDSQXAO-1T00-GN6ZN is a 1TB microSDXC card officially licensed for all Nintendo Switch systems. It delivers read speeds up to 100MB/s and write speeds up to 90MB/s under the UHS-I interface. The card adds substantial space for digital games, screenshots and videos in a single, compact form factor.
This card suits players who prefer to keep their entire library on the console without swapping media. It is not for users who need higher sustained write throughput for 4K video capture or professional workflows. Buyers using devices that only support the older microSDHC standard should look elsewhere.
The UHS-I rating sets maximum read at 100MB/s and write at 90MB/s, which determines load times and install speeds on the Switch. Any device limited to slower bus speeds will not reach these rates. Match the card to hardware that can utilise the UHS-I specification for full benefit.

Other versions of this model
The 1TB version holds the largest game library plus screenshots and videos in one card; choose a smaller size only if you plan to keep fewer titles installed at once.
Games load at up to 100MB/s read and 90MB/s write, so large titles launch faster and downloads finish sooner than on slower cards.
The card is UHS-I Class 10 and officially licensed, guaranteeing compatibility and the stated 100MB/s read and 90MB/s write speeds on every Switch model.
