Picking the right card
Size first
Phones, consoles, drones and action cams take microSD. Most full-size cameras take SD. Check the slot before anything else.
Then speed class
- V30 / U3
- 30 MB/s minimum sustained write. The usual floor for 4K video.
- V60 / V90
- For high-bitrate cameras. Your camera's manual says which.
- A1 / A2
- Rated for running apps and games off the card.
Capacity last
Buy for the device's maximum, not the biggest number. Older devices may not read cards above their limit; it's listed in the specs.
