Sandisk 128GB microSDXC for Nintendo Switch

SanDisk 128GB microSDXC Licensed for Nintendo Switch gives your console up to 128GB of fast, official expandable storage so you can keep more games, saves, screenshots and captures on one card.

If your Nintendo Switch, Switch Lite, or Nintendo Switch OLED is running low on space, this officially licensed SanDisk microSDXC card adds large, reliable storage without slowing down load times. Designed for gamers, the card delivers high read/write performance so downloads, updates and game loads happen faster than generic cards. It’s backed by SanDisk’s long-term warranty and explicitly intended for Nintendo Switch family systems (not the forthcoming Nintendo Switch 2).

How much extra game storage will 128GB give me?

128GB provides room for dozens of digital titles, depending on each game's size, plus screenshots and short video clips. Actual usable capacity is slightly less than 128,000,000,000 bytes because of formatting and system files.

• Holds many standard indie and mid-size titles; larger AAA games vary from a few GB to tens of GB.
• Store updates and DLC alongside base games to avoid juggling cartridges.
• 128GB is a balanced choice for players who download regularly but don’t need mass archive-level storage.

Will this card make my games load faster?

The SanDisk card offers up to 100MB/s read and up to 90MB/s write speeds for the 128GB model, which helps shorten load times compared with slower microSD cards. Performance depends on the console’s interface and real-world conditions, but it is tuned to work well with the Switch family.

• Up to 100MB/s read speed helps reduce level and texture load delays.
• Up to 90MB/s write speed speeds up saving and capture storage.
• Speeds measured under internal testing; results vary by device and usage.
