Top MicroSD Express Cards for Nintendo Switch 2

Author : Lucas May 13,2025

With the Nintendo Switch 2 on the horizon, it's crucial to consider its built-in storage capacity of just 256GB. For avid gamers looking to store multiple games without the hassle of constant uninstalling and reinstalling, expanding the storage is a must. However, unlike its predecessor, the Nintendo Switch 2 requires a MicroSD Express card for expansion. These cards are faster but come at a higher price than traditional UHS-based SD cards.

Currently, the market for MicroSD Express cards is limited, with only a few models available. These cards, although not widely adopted by creative professionals yet, are poised to become more prevalent with the imminent launch of the Switch 2. Keep in mind that since the console hasn't been released, the performance of these cards with the Switch 2 remains untested. However, they are produced by reputable manufacturers known for their quality storage solutions.

Why MicroSD Express?

The Nintendo Switch 2's mandate for MicroSD Express cards for storage expansion may seem puzzling, but it aligns with the console's advanced technology. The system uses UFS flash storage, similar to what's found in modern smartphones, which is significantly faster than the eMMC drive in the original Switch. By requiring MicroSD Express, Nintendo ensures that developers can rely on consistent high-speed storage, whether games are stored internally or on an expansion card.

It's worth noting that regular MicroSD cards can only be used for transferring screenshots and videos from your first-generation Switch. Unlike the PS5, which supports last-generation games on slower external drives, the Nintendo Switch 2 offers no such flexibility. If you want to expand your storage, you'll need a MicroSD Express card.

MicroSD Express FAQ

How fast is MicroSD Express?

MicroSD Express cards are significantly faster than their predecessors, thanks to their use of PCI Express 3.1, the same interface used by SSDs in PCs. While full-sized SD Express cards can reach read speeds up to 3,940MB/s, MicroSD Express cards top out at 985MB/s. This is still much faster than the older MicroSD cards used by the original Nintendo Switch.

How long will a MicroSD Express card last?

Like any SD card, MicroSD Express cards have a limited lifespan, typically lasting 5-10 years. Their durability depends on usage and environmental conditions. Always ensure to back up important data, as these cards are not designed for long-term storage.
