What is microSD Express?
MicroSD Express was originally developed to provide SSD-like speeds in a compact form. Unlike traditional microSD cards, which use the UHS-I interface, microSD Express integrates NVMe technology, allowing for significantly faster read and write speeds.
Despite its advantages, microSD Express never gained widespread adoption because:
- Higher cost – These cards are more expensive than standard microSD.
- Limited device support – Few consumer electronics supported the format.
- Standard microSD was “good enough” – Most devices didn’t require ultra-fast storage speeds.
Now, with the Nintendo Switch 2, microSD Express is finally seeing mainstream adoption.
Why does the Switch 2 need microSD Express?
Nintendo’s decision to use microSD Express is driven by the increased demands of modern gaming. The Switch 2 features:
- Higher-resolution textures – Games require faster data streaming.
- Improved load times – NVMe speeds help reduce waiting times.
- Larger game sizes – Some titles exceed 50GB, making fast storage essential.
By using microSD Express, the Switch 2 ensures smooth performance for digital games.
