4 . MicroSD cards are common in smartphones, tablets, and action cameras. Finding the right microSD card doesn’t have to be difficult — we can help you find the best microSD cards for your needs.

Samsung EVO Select MicroSD Memory Card

This microSD card can handle the needs of nearly any device and any type of user, and it offers the fastest speeds and highest storage of the cards we considered while keeping a low price tag. The write speed isn’t provided for this microSD card, which isn’t uncommon — manufacturers often focus on read speed instead because it’s where you’ll notice a la g if there is any.

SanDisk 256GB Extreme Memory Card

Bob Sacha, a photographer and associate professor of video storytelling, recommends getting a card like this one. “This card may have a lower read speed and write speed, but it works in all the cameras I use,” he says. This microSD card is also shockproof, waterproof, and able to withstand high temperatures, which makes it suitable for action cameras.

SanDisk Ultra 512GB Memory Card

If you’re into portable gaming, and are planning on keeping more than a game or two on hand at any given time, you’ll need enough storage to back that up. The SanDisk Ultra 512GB is just a version of our pick for Switch gaming with more storage, since the read and write speeds are perfectly fine for gaming. It also has plenty of storage to work with a 4kdrone (无人机) or a home security camera.

PNY U3 Pro Elite 512GB MicroSD Card

Where write speed really comes into play is when you’re recording video. That’s also when you’ll want to pay attention to the video class, which measures the minimum levels of write speed for recording 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 the PNY Pro Elite.
