Is this card fast enough for 4K video?

Yes. The V30 and U3 ratings guarantee a minimum 30 MB/s write speed, which meets the requirement for most 4K action cameras and drones.

Will it work in a phone?

Yes, if the phone has a microSD slot. The A1 rating helps apps stored on the card load faster on Android.

It is a microSDHC card. Whether an adapter is included depends on the pack, so check the box contents before buying for a full-size SD slot.

Roughly 40 to 60 minutes at typical 4K bitrates, depending on the camera. Plan on offloading footage often.

Yes for video. The Extreme has higher sustained write speeds and a V30 rating, while the Ultra is aimed at simpler photo and HD use.

Yes. It works in the Switch and Switch Lite, though 32GB adds only modest space beyond the console's built-in storage.

Rated 4.8 out of 5 from 1,800 ratings.
