The Best MicroSD Card for Your Phone, Camera, or Nintendo Switch

A selection of SD cards

MicroSD cards are almost identical to SD cards in every way except, instead of DSLRs and point and shoots, they’re more commonly used in devices like phonestablets, GoPros, and the Nintendo Switch. While you may be tempted to pick up any microSD card with a lot of storage and assume it’s the best one, the experts we consulted say that’s a risky proposition. They tell us it’s important to find a microSD card with a good balance of read speed, write speed, and storage.

Storage capacity is how much information your card can hold — how many games, how many hours of video footage, etc. — and it’s usually measured in gigabytes (although some microSD cards now hold up to a terabyte). Write speed is how fast a card can create and write a file, and it’s measured in megabytes per second. Read speed is measured the same way, and it’s how quickly your card can access the file you’re trying to open. We spoke with three experts: our colleagues at the Verge, a photo and video pro at B&H Photo, and a professor of video storytelling at the Graduate School of Journalism at CUNY. Here are their picks for the best microSD cards available.

Best overall microSD card

Samsung EVO Select 512GB MicroSD

It’s a little pricey, but this card can handle the needs of nearly any device and any type of user. It has a maximum read speed of 100 MB/s and a maximum write speed of 90 MB/s. It’s also shockproof, waterproof, and can withstand extreme temperatures. At our sister site, the Verge, our colleagues like this card because “it has the obvious advantage when it comes to storage capacity.” They also point out that “if you plan to use [it] for both gaming and recording video, it’s good to know that it can perform both functions well.”

Best microSD card for gaming

SanDisk Ultra 128GB MicroSD

Although Joseph Palma at B&H Photo likes Nintendo’s official SD card, which has read speeds up to 100 MB/s and write speeds up to 90 MB/s, he actually recommends saving a little money and buying this 128 GB card from SanDisk. Why? SD cards in gaming devices are mostly “used to store the game info and read the game, not write beyond save files and installation,” he says. So the extra speed is unnecessary. This card has a lower maximum read speed of 80 MB/s and a much slower write speed of 10 MB/s, but that’s still plenty for typical gaming. It’s what Palma uses for his own Switch.

Best (high-capacity) microSD Card for gaming

SanDisk 512GB Ultra MicroSDXC UHS-I Memory Card

If you plan to download a lot of games and need a card with more storage, the Verge recommends picking up a 512 GB SanDisk microSD card, which it considers to be a good buy “for a low-cost, high-capacity card.”

Best microSD card for cameras

PNY U3 Pro Elite 512GB MicroSD Card

Where write speed really comes into play is recording video. You need a card with great specs, so pay attention to video class, which measures the minimum levels of write speed for recording video, and Ultra High speed class, which tells you what type of video, HD or UHD, the card can handle. Video class is marked with a V on the front of the card and ranges from V6 to V90. Palma says V30 should be sufficient for shooting ultra-high-definition 4K video. Ultra High Speed class is a number inside a U on the front of the card. A U1 card should be able to handle 1080p recording without any issues, but if you want to record 4K, get a U3 card like this one. The Verge likes this PNY 512 GB Pro Elite microSD card, which has up to 100 MB/s read speed and a 90 MB/s write speed, so it can always keep up.

Most versatile microSD card

SanDisk 400GB Extreme MicroSD

Bob Sacha, a photographer and associate professor of video storytelling at the Graduate School of Journalism at CUNY, recommends getting a card like this one that can handle all types of devices. He shoots with many different cameras and likes to have a microSD card that can work with all of them. For cameras that take standard SD cards, “I often will put that microSD card into an SD-card adapter” — like this one — “and then use it in my DSLR or video cameras,” he says. “It’s a great trick to have one set of cards that will work in all the cameras I use.”
