Our choice

The Samsung card from Samsung is easy to find, quick, and inexpensive compared with competitors. It has a storage capacity of 512 GB, providing space for numerous game downloads or hours of 4K drone footage.
The Samsung Pro Plus is the fastest card we tested in this group of microSDXC cards and is our pick for most users. It is quick enough for storing 1080p, 4K, and up to 5K video in action cameras and drones, it adds ample storage to smartphones, game systems, and tablets, and it can function as the boot drive or storage for a kit PC such as the Raspberry Pi. With 512 GB, you have enough space for a vast games library on the Nintendo Switch or the Steam Deck.
Budget option

This microSD card is fast, attractively priced, and suitable for phones, tablets, game consoles, and more. It has less capacity than our top pick, but it can still double the storage in a Switch.
The SanDisk microSDXC Card for Nintendo Switch is available in multiple capacities. In a previous round of testing, the 128 GB version performed the fastest and became our top pick at the time. We recommend it for aspiring drone pilots, individuals needing to add storage to security cameras, new video game players with their first Nintendo Switch, and Switch owners solely interested in downloading and playing Nintendo’s main titles.
