- Is this card fast enough for 4K video?
- Yes. Its V30 and U3 ratings are designed for 4K recording in action cameras, drones and phones. Sustained writes are fine for typical clips, though long continuous recording is where faster cards pull ahead.
- How does it compare with the SanDisk Ultra?
- The Extreme has higher write speeds and is the better choice for video and gaming. The Ultra is cheaper and fine for photos and music, but it is slower when writing large files.
- Will it work in a Steam Deck or Nintendo Switch?
- Yes. It is a standard microSDXC card and works in both, as well as in Android phones and most action cameras. The Switch accepts microSDXC cards of this capacity.
- Does it come with an SD adapter?
- Most retail versions include a full-size SD adapter so you can use it in a laptop's SD slot. Check the specific pack, since some bulk or OEM versions ship card-only.
- Is it compatible with UHS-II devices?
- It fits UHS-II slots but runs at UHS-I speeds, so you will not get the faster bus. It is a sensible match for UHS-I cameras, drones and phones.
- Is the 128GB version enough for a GoPro?
- It holds several hours of 4K footage depending on bitrate and settings. Heavy 4K or high-frame-rate shooters may want a larger capacity for long trips.
