The best MicroSD cards for Nintendo Switch 2025

Grabbing one of the best MicroSD card slots for Nintendo Switch is a pretty much must-have purchase in 2025 as the dear old Switch’s 25.9GB of accessible space isn’t enough to keep multiple games, and to make matters worse, sometimes you can’t fit larger AAA games onto it at all. To this end, the likes of the 512GB Kingston Canvas Select Plus is one of our favourites in the UK, while folks in the USA can benefit from the 512GB TeamGroup Pro Plus.

As well as simply recommending cards for you to try, we’ll also share the results of our load time tests for different games, and also the best ways to move your data over from the internal storage to the SD card, and from the card to the internal storage, too.

Anyways, enough chat – here’s our top picks for the best MicroSD cards for Nintendo Switch!

Of course, capacity is only half of the equation – what about speed? Well, here the Switch isn’t quite so future-proof. The console only supports UHS-1 cards, which have a maximum possible speed of 104MB/s, compared to the 312MB/s speed limit of the more modern UHS-2 standard. However, our testing revealed only a tiny differential between the slowest and fastest UHS-1 MicroSD cards on the Switch, so our recommendations are tailored towards capacity and value rather than speed.
