Best MicroSD Express Cards for Nintendo Switch 2 Storage Expansion

The Nintendo Switch 2 is launching soon with just 256GB of internal storage. To avoid constant game uninstalls and reinstalls, expanding storage is essential. Unlike its predecessor, the Switch 2 requires MicroSD Express cards, which offer faster speeds but come at a higher cost than standard UHS-based SD cards.

Though MicroSD Express cards have been available for some time, their market presence is limited, as they’ve seen minimal adoption among creative professionals. With the Switch 2’s release approaching, expect a surge in available MicroSD Express options to meet demand.

Since the console isn’t out yet, these MicroSD Express cards for the Nintendo Switch 2 haven’t been tested. Still, they come from trusted brands known for reliable storage solutions.

Why Choose MicroSD Express?

The Nintendo Switch 2 mandates MicroSD Express cards for storage expansion, a departure from standard MicroSD cards. While Nintendo hasn’t detailed its reasoning, the decision likely ties to performance needs.

The console’s internal UFS flash storage, similar to that in modern smartphones, far outpaces the eMMC drive in the original Switch. Nintendo likely requires MicroSD Express to ensure consistent high-speed performance, whether games are stored internally or on an expansion card.

Regular MicroSD cards are limited to storing screenshots and videos from the original Switch. Unlike the PS5, which supports slower external drives for older games, the Switch 2 offers no such flexibility—MicroSD Express is the only option for storage expansion.

1. Lexar Play Pro

Top MicroSD Express Card

Lexar Play Pro

Among the few MicroSD Express cards available, the Lexar Play Pro stands out for its speed and capacity. With read speeds up to 900MB/s and up to 1TB of storage, it’s the premier choice for Switch 2 users. However, high demand has made it difficult to find in stock.

As Switch 2 excitement stabilizes, availability should improve. For the best storage experience, monitor the Lexar Play Pro, especially the 1TB model, and grab it when available. Currently, Adorama offers it on backorder until July.

2. SanDisk MicroSD Express

Most Accessible MicroSD Express Card

SanDisk MicroSD Express

SanDisk is a leading name in SD cards, and its MicroSD Express card is no exception. Offering up to 256GB of storage—matching the Switch 2’s internal capacity—it’s a solid choice for doubling your space. Its read speed of 880MB/s is slightly slower than the Lexar Play Pro, but the difference is negligible for games like Mario Kart World.

With strong availability, the SanDisk MicroSD Express is ideal for those wanting a reliable, hassle-free purchase. More options may emerge once the console launches, but this card is a dependable choice now.

3. Samsung MicroSD Express for Switch 2

Nintendo’s Official Choice

Nintendo Samsung MicroSD Express

Samsung’s MicroSD Express card, sold directly by Nintendo, carries the console maker’s approval. However, details like storage speed and whether the 256GB model is the only option remain unclear.

While specs are sparse, the Nintendo branding offers reassurance. Further details from Samsung are pending, and this section will be updated once available.

MicroSD Express FAQ

How Fast Is MicroSD Express?

MicroSD Express cards significantly outpace traditional SD cards, thanks to their PCI Express 3.1 interface, similar to SSDs in PCs. While full-sized SD Express cards can reach speeds up to 3,940MB/s, MicroSD Express cards max out at 985MB/s—still a major leap over the original Switch’s MicroSD cards.

How Long Do MicroSD Express Cards Last?

Like all SD cards, MicroSD Express cards aren’t designed for long-term data storage and have a finite lifespan. Depending on usage and environmental factors, they typically last 5-10 years. Always back up critical data to ensure longevity.
