The Nintendo Switch 2 is on the horizon, and with its launch imminent, it's important to note that it comes with only 256GB of built-in storage. For avid gamers looking to amass a collection of games without the hassle of constant uninstalling and reinstalling, expanding that storage is crucial. Unlike its predecessor, the Nintendo Switch 2 requires a MicroSD Express card for additional storage. These cards are not only faster but also more expensive than the traditional UHS-based SD cards.
MicroSD Express cards have been around for a while, but their market presence is limited, as they haven't been widely adopted by creative professionals. However, with the imminent launch of the Switch 2, we can expect a surge in the availability of these cards. Keep in mind, though, that since the system isn't out yet, I haven't had the chance to test any of these cards. Nonetheless, they come from reputable manufacturers known for their high-quality storage solutions.
Why MicroSD Express?
The Nintendo Switch 2 mandates the use of MicroSD Express cards for storage expansion, and while Nintendo hasn't explicitly stated why, the reasoning seems clear. The console features UFS flash storage, similar to what's used in 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.
For those hoping to use regular MicroSD cards, they're limited to storing screenshots and videos from the first-generation Switch. Unlike the PS5, which allows for slower external drives to store last-gen games, the Switch 2 offers no such flexibility. If you're looking to expand storage on the Nintendo Switch 2, a MicroSD Express card is a must.
1. Lexar Play Pro
The Best MicroSD Express Card

Out of the available MicroSD Express cards, the Lexar Play Pro stands out as the fastest and most capacious option. Boasting read speeds up to 900MB/s and storage capacity up to 1TB, it's the top choice for expanding your Switch 2's storage. However, due to high demand, it's currently out of stock. Keep an eye on it, especially the 1TB version, and consider ordering through Adorama, which has it on backorder until July.
2. SanDisk MicroSD Express
The MicroSD Express Card You Can Actually Buy Right Now

SanDisk, a well-known SD card manufacturer, offers a MicroSD Express card that's currently available. While it's limited to 256GB, effectively doubling your Switch 2's internal storage, it's a reliable and affordable option. With a read speed of up to 880MB/s, it's slightly slower than the Lexar Play Pro but still offers a significant boost. If you're looking to buy now, this is a great choice, though more options will be available once the console is in hand.
3. Samsung MicroSD Express for Switch 2
The Official Option We Know Very Little About

Samsung's MicroSD Express card, sold directly by Nintendo, adds an official touch to your storage solution. However, details on its speed and capacity are scarce, with only a 256GB model currently known. While specifics are pending, the comfort of having Nintendo's endorsement might sway your decision. I've reached out to Samsung for more information and will update this article once I have it.
MicroSD Express FAQ
How fast is MicroSD Express?
MicroSD Express cards are significantly faster than traditional SD cards due to their use of the PCI Express 3.1 interface, similar to SSDs in PCs. While full-sized SD Express cards can reach up to 3,940MB/s, MicroSD Express tops out at 985MB/s, still a substantial improvement over 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 finite lifespan, typically lasting between 5-10 years, depending on usage and environmental factors. It's wise to back up important data regularly to avoid losing it when the card reaches the end of its life.
