Is this card fast enough for 4K video?

Yes. Its write speed handles 4K recording in phones, action cameras and drones. Very high-bitrate modes in pro cameras may need a UHS-II card.

Does it work in a Nintendo Switch?

Yes. The Switch uses UHS-I microSD cards, and this one gives fast load times and plenty of room for downloaded games.

Is it better than the PRO Plus?

The PRO Ultimate is the higher tier, with faster rated speeds and the same six-proof protection. The PRO Plus remains a solid cheaper option for lighter use.

Does it come with an SD adapter?

Some packs include a full-size SD adapter and some do not. Check the pack contents before buying if you need one.

Will it work in a UHS-II card reader?

Yes, but it runs at UHS-I speeds. A UHS-II reader will not make this card faster.

Our take on the Samsung 512GB PRO Ultimate microSDXC UHS-I Memory Card

The Samsung PRO Ultimate is Samsung's top-tier UHS-I microSD card, built for action cameras, drones, phones and handheld consoles. It stands out with fast sequential reads and writes for a UHS-I card, plus Samsung's six-proof protection against water, temperature, X-rays, magnets, drops and wear. It suits people who move large 4K video files and want a card that holds up outdoors. Against UHS-II cards it is slower in the fastest card readers, but it works in far more devices and costs less than UHS-II media.
