Is this card fast enough for 4K video?

Yes. It is V30 rated, which means sustained writes of at least 30MB/s, enough for 4K video in most drones and action cameras. Rated writes go up to 130MB/s.

Will it work in a Nintendo Switch or Steam Deck?

Yes. Both use microSDXC cards, and the A2 rating helps app and game load times. Format the card in the device before first use.

Do I need a special reader to get 190MB/s?

Yes. The top read speed needs a UHS-I reader that supports the higher bus speed, such as SanDisk's PRO-READER. A basic USB reader will be slower.

Is the 1TB version slower than the smaller capacities?

No. SanDisk rates the 64GB to 1TB cards at the same 190MB/s read and 130MB/s write speeds.

Just the microSDXC card. An SD adapter and reader are not included.

Is it compatible with regular SD slots?

Only with a microSD-to-SD adapter. The card itself is microSDXC and fits microSD slots.
