Key takeaways
- Express vs standard microSD: Only microSD Express cards deliver the NVMe-class speeds the Switch 2 needs for game storage; standard UHS-I cards are too slow and will not work the same way.
- Read and write speed: Look for read speeds near 900MB/s and healthy write speeds; faster cards cut load times and make installs quicker, which is the whole point of Express.
- Capacity: 256GB is a solid starting point and 512GB gives serious headroom for a large digital library; buy more than you think you need since games keep growing.
- Brand reliability: Stick with established memory brands for firmware quality and warranty support, since a failing card can take your saves and downloads with it.
- Device compatibility: Confirm the card is rated for your specific device; most are marketed for Switch 2 but also work as fast storage in cameras and other Express-capable hosts.

Frequently Asked Questions
Do I need a microSD Express card for the Switch 2?
Yes. The Switch 2 requires microSD Express cards to store and run games properly, as standard microSD cards lack the speed the console needs. Older cards may only work for screenshots or media.
How fast are microSD Express cards?
The best Express cards reach read speeds around 880 to 900MB/s, several times faster than the old UHS-I standard. This dramatically reduces game load times and makes installs feel much quicker.
What capacity microSD Express card should I buy?
256GB is a comfortable starting point, while 512GB is ideal for a large digital library. Because modern games are large and only getting bigger, buying extra capacity now saves you from upgrading again soon.
Can I use a microSD Express card in other devices?
Yes, Express cards work in any host that supports the standard and are backward compatible with regular microSD slots, though they will run at slower UHS-I speeds outside of Express-capable devices.
Final Thoughts
For most Switch 2 owners, the SanDisk 512GB microSD Express strikes the best balance of speed, capacity, and brand trust, while the Lexar Play PRO edges ahead on raw read speed. If value is your priority, the TEAMGROUP APEX and PNY cards deliver Express performance for less. Whatever you choose, make sure it is a genuine Express card, because on the Switch 2 nothing else will do the job.
