Is this card good enough for 4K video?

No. Its U1 rating targets Full HD; 4K and high-bitrate recording want a U3 card such as the SanDisk Extreme.

Will it work in a Nintendo Switch?

Yes. The Switch accepts microSDXC cards, and the A1 rating helps with game load times.

How much space will I actually get?

Expect roughly 460GB usable after formatting, since card makers count 1GB as one billion bytes.

Does it come with an SD adapter?

No. The card ships on its own, so you need a microSD slot or a separate adapter for full-size cameras.

How is it different from the SanDisk Extreme?

The Extreme has a U3 rating and much faster sustained writes for 4K video and burst shooting. This Ultra is the cheaper, slower storage card.

Can I use it in a dashcam?

Yes at 1080p. For continuous loop recording, a high-endurance card is the safer choice.

Our take on the SANDISK Ultra 512GB MicroSD Memory Card

The SanDisk Ultra 512GB is a microSDXC card built for phones, tablets, cameras and laptops. It carries a U1 and Class 10 rating with A1 app performance, and SanDisk rates it at up to 195MB/s read for this capacity. That makes it a storage-first card: fine for Full HD video, photos, music and app data, but not the pick for 4K recording or sustained large-file writes. Rivals like the SanDisk Extreme and Samsung Pro lines cost more and write faster, while this card competes on capacity per dollar and everyday reliability.
