  • TypemicroSDXC
  • Officially licensed for Nintendo Switch so it works straight out of the box

  • Class 10 speed rating supports smooth gameplay recording
  • U3 video speed class enables 4K capture without dropped frames
  • SanDisk brand delivers reliable flash storage for long-term use

Designed for Nintendo Switch

This officially licensed SanDisk microSDXC card adds 512GB of storage to the Nintendo Switch console. It lets players keep a large library of digital titles on a single card. The Class 10 and U3 ratings support fast read speeds for smooth gameplay loading.

Simple insertion with one common error

Installation only requires inserting the card into the console's slot until it clicks. The most frequent mistake is not pushing the card in fully, which prevents the system from recognising the storage. No tools or formatting steps are needed before first use.

UHS-I bus limits maximum throughput

The card uses the UHS-I interface, which caps sequential transfer speeds below what UHS-II or UHS-III cards can achieve. Large game files will take longer to copy compared to faster bus standards. The 512GB capacity also means a single card failure risks losing the entire library.

Questions about this item

How can I verify the card is performing at its rated U3 and Class 10 speeds after installing it in my Switch?

The console will run games and save data directly from the card without lag or errors, confirming the 10 MB/s minimum write speed and U3 video rating are active.

What does the package contain and is a separate adapter needed for the console slot?

The box includes the 512GB microSDXC card itself; the Nintendo Switch reads microSD directly so no extra adapter is required.

Should I choose this 512GB officially-licensed version or look for a different capacity?

Pick this 512GB model if you want the largest single-card capacity offered in the licensed line so your whole library fits on one card.
