Switch 2 requires MicroSD Express cards for game storage. Regular microSD cards are not supported for gameplay.
Lexar Play Pro leads in speed and capacity, while SanDisk and Samsung offer more accessible and budget-friendly options.
Choosing the right card impacts performance, so look for at least 880MB/s read speed and enough space to match gaming needs.
Nintendo Switch 2 is expected to arrive with 256GB of internal storage. Sounds manageable, until large titles and updates fill it up. With the system now supporting only MicroSD Express cards for game storage, expanding memory isn't optional anymore; it's essential.
Unlike regular microSD cards, which are now limited to storing screenshots and videos, MicroSD Express uses PCIe 3.1 technology to deliver SSD-like speeds in a compact form. The market is still catching up, but a few top-performing cards have already made their mark. Here are the best picks for your console.
Estimated Price: $140–$170 for 1TB
Lexar Play Pro leads the pack with read speeds up to 900 MB/s and storage up to1 TBB. It’s the card of choice for hardcore gamers, those who download multiple 1 TB titles or never delete a game. Performance is smooth, loading times stay short, and updates run without delay. The downside? It’s hard to find. Demand is high, and many retailers are showing it as backordered. Adorama currently lists it for July delivery. Worth the wait for those wanting top-tier performance.
