Key takeaways
- Confirm it is Express, not UHS: Only microSD Express cards, like the SanDisk 512GB Express, deliver the NVMe speeds the Switch 2 relies on.
- Capacity for your library: 256GB suits most players, but power users downloading big titles should look at 512GB or the SanDisk 1TB card.
- Sustained write speed: Peak read numbers grab headlines, but sustained write, such as the SanDisk 1TB’s 745MB/s, matters for large installs.
- Device compatibility: Express cards are backward compatible with UHS-I devices at reduced speed, so they remain useful beyond the console.
- Value per gigabyte: Weigh the PNY and Integral 256GB options against the premium SanDisk and Lexar cards to find your sweet spot.
What's inside
The arrival of the Nintendo Switch 2 made microSD Express the storage format to know in 2026. Unlike the older UHS-I cards, these tiny cards use the NVMe and PCIe protocols to reach solid-state speeds, which is exactly what the new console needs to load games from expandable storage without a painful wait.
Because Switch 2 only accepts microSD Express, choosing the right card is less about brand loyalty and more about capacity, sustained write speed, and value per gigabyte. The picks below are all genuine Express cards ready to drop into your console or other high-speed devices.

Frequently Asked Questions
Will a regular microSD card work in the Switch 2?
Only for saving screenshots and videos. To store and play games from the card, the Switch 2 requires a genuine microSD Express card like the ones listed here.
How much capacity do I need?
256GB handles a modest library, while 512GB suits most players. Choose 1TB if you download many large titles and rarely want to delete anything.
Are microSD Express cards worth the higher price?
For the Switch 2, yes, because it is the only supported expandable format. The dramatic speed jump over UHS-I also benefits any device that can read the protocol.
Can I use these cards in older devices?
Yes. microSD Express cards are backward compatible with UHS-I slots, though they run at the slower UHS-I speed in those devices rather than their full Express rate.
Final Thoughts
For Switch 2 owners in 2026, a microSD Express card is essential rather than optional. The SanDisk 512GB Express is the balanced all-rounder, the SanDisk 1TB is the no-compromise capacity king, and the PNY or Integral 256GB cards keep costs down. Match capacity to your download habits and enjoy near-instant loading from expandable storage.
