• Download more digital games and updates
• Keep your library without deleting older titles
• Store screenshots, video captures, and DLC hassle-free
• Reduce storage stress and manage your games more easily

What Memory Cards Does the Nintendo Switch Support?

Nintendo Switch systems support three types of microSD cards:

• microSD (up to 2GB) — not practical today
• microSDHC (4GB to 32GB) — fills up quickly
• microSDXC (64GB and up) — recommended for most gamers

Tip: For the best experience on current Switch models, choose a reliable microSDXC UHS-I card from a trusted brand and buy from a reputable seller to avoid counterfeits.

How Much Storage Do You Need?

Choose capacity based on how you buy games (digital vs physical) and how large your library is:

• 128GB — casual users (a few digital titles + updates)
• 256GB — best overall balance for most players
• 512GB+ — heavy digital libraries, lots of AAA titles, families sharing a console

Practical rule: If you buy digital often, start at 256GB. If you frequently download AAA titles, aim for 512GB to avoid running out of space.
