A microSD card that worked in the original Nintendo Switch is not automatically the right storage choice for Nintendo Switch 2. Nintendo’s UK hardware page distinguishes microSD Express compatibility from a narrower use of an older card to bring across screenshots and videos. The important decision is the job the card needs to perform, rather than its familiar size or appearance.

Game storage and media import are different tasks

The Nintendo UK page states that Switch 2 is compatible with microSD Express cards. It says an older microSD card from a Switch cannot be used to save or load digital games on Switch 2, while allowing the import of captured screenshots and videos. It also notes an internet system update for first use of a microSD Express card.

The exception does not turn the older card into general game storage. A reader planning a transition should therefore separate the media-import task from the storage-expansion task. Treating them as one operation could lead to buying or reusing a card for a purpose the page does not support.

Read the standard, not just the capacity

A large capacity label does not answer the compatibility question by itself. Before comparing storage sizes, identify whether the card is the documented type for the console. A product photo or a listing headline may emphasise capacity while making the standard less prominent, so the full specification matters.

This article has not inspected a retailer listing or verified a particular card. A proposed purchase note can record the exact product identifier, the stated standard and the console model. That gives the buyer a concrete set of details to compare with the manufacturer’s guidance without inventing a recommended brand or a current offer.

Plan the transition as separate decisions

For a hypothetical owner with an existing Switch card, list what needs to move: captured media, digital-game data or other console information. Then follow the corresponding current Nintendo support route. The hardware overview is useful for choosing the card type, but it is not a complete migration procedure for every category of data.

Keep any data-changing operation separate from the purchasing decision. Confirm the relevant official instructions before deleting, formatting or altering material. No such operation was performed here, and this article does not provide an improvised transfer process or a guarantee that a particular set of files can be recovered.

A faster standard is not a tested result

Nintendo describes microSD Express as faster at reading and writing than earlier microSD standards. That manufacturer description should not be turned into a measured game-loading improvement for a particular card or title. Such a comparison would need named hardware, software and test conditions.

The useful conclusion is narrower and practical: choose the documented card standard for Switch 2 game storage, and treat old-card screenshot or video import as a separate function. The UK source supplies that distinction. Current card availability, retailer identity, capacity suitability and migration arrangements remain decisions that require their own evidence; no benchmark or hands-on result is invented.

Name the card task before comparing capacity

Field	Record or question
Digital game storage	Use the documented microSD Express standard; record the exact card identity.
Old-card media	Treat import of captured screenshots/videos as a separate exception.
First use	Nintendo documents an internet system update; use its current instructions before data changes.
