The Nintendo Switch 2 is set to launch soon, and if you're planning to purchase it, it's important to note that the console comes with just 256GB of internal storage. If you’re looking to install multiple games without constantly uninstalling and reinstalling titles, expanding your storage space will be essential. However, unlike the original Switch, the new system requires a MicroSD Express card for storage expansion — these cards are faster than traditional UHS-based SD cards, but also more expensive.

Why MicroSD Express?

While Nintendo hasn't officially explained its decision to mandate MicroSD Express cards for the Switch 2, the reasoning seems tied to performance. The internal flash storage in the new console uses high-speed UFS technology, similar to what’s found in modern smartphones. By requiring MicroSD Express cards, Nintendo ensures developers can rely on consistent, fast load times whether a game is installed internally or on an external card.

This marks a shift from previous systems like the original Switch, which supported standard MicroSD cards, and even the PS5, which allows slower drives for backward-compatible titles. On the Switch 2, regular MicroSD cards are only useful for transferring screenshots and videos from the first-gen model — nothing more.

Top MicroSD Express Card Options for the Nintendo Switch 2

1. Lexar Play Pro

• Pros: Up to 1TB capacity, fastest read speeds at 900MB/s
• Cons: Currently out of stock, most expensive option

The Lexar Play Pro is currently the fastest and highest-capacity MicroSD Express card available, offering up to 1TB of storage and read speeds reaching 900MB/s. While it’s the best choice for maximizing both speed and storage, availability has been limited due to high demand. You may find it on backorder through retailers like Adorama, with availability expected around July.

2. SanDisk MicroSD Express

• Pros: Readily available, trusted brand name
• Cons: Limited to 256GB capacity, slightly slower than Lexar (880MB/s)

For those who prefer to buy now rather than wait, the SanDisk MicroSD Express card is the most accessible option at the moment. Although it only offers up to 256GB — matching the internal storage of the Switch 2 — and has slightly lower read speeds than the Lexar Play Pro, the difference won’t be noticeable during gameplay. This makes it a solid, reliable choice for early adopters.

3. Samsung MicroSD Express (Nintendo-Branded Option)

• Pros: Officially licensed by Nintendo, made by a reputable manufacturer
• Cons: Specs not yet confirmed, not available at time of writing

Samsung is reportedly producing a branded MicroSD Express card for Nintendo, likely to be sold directly through official retailers like Best Buy and GameStop. While no performance details have been released, having Nintendo’s endorsement may provide peace of mind for many users. More information will follow once the product becomes available.

MicroSD Express FAQ

How Fast Is MicroSD Express?

MicroSD Express cards offer significantly faster performance compared to older MicroSD standards. They utilize the PCIe 3.1 interface, the same used by SSDs in PCs, allowing for much higher data transfer rates. While full-sized SD Express cards can reach speeds up to 3,940MB/s, MicroSD Express models max out at around 985MB/s. This is still substantially faster than the older eMMC storage used in the original Nintendo Switch.

How Long Will a MicroSD Express Card Last?

Like all flash storage, MicroSD Express cards are not designed for permanent archival use. Their lifespan typically ranges between 5–10 years depending on usage conditions. Frequent read/write cycles, exposure to heat, and physical damage can affect longevity. It’s wise to regularly back up important data and plan for eventual replacement.
