Frequently asked questions
- What do the speed classes U3, V30 and A2 mean?
- U3 and V30 guarantee a sustained write of 30 MB/s, enough for 4K video. V60 and V90 are for professional cameras with high bitrates. A1 and A2 rate random-access speed and suit cards in a phone or game console that run applications. For a camera or drone we recommend at least V30.
- SD, microSD or CFexpress?
- Go by the slot in the device: cameras and laptops take SD, phones, drones, action cameras and consoles microSD, the newest professional cameras CFexpress type A or B. A microSD card can be used in an SD slot with the included adapter. Capacities above 32 GB are the SDXC format, which older devices may not support.
- Which card capacity should I choose?
- For a phone and photos 64 to 128 GB is enough; for 4K video 256 GB or more, as an hour of 4K takes roughly 20 to 45 GB. Check the maximum supported capacity in the device manual. For a camera two smaller cards are safer than one large one: a failure does not cost you everything.
- Can I use the camera card in a dashcam or a phone?
- Yes, if the size fits, but format the card in the new device itself before use, not in a computer. For continuously recording cameras and recorders choose a card labelled High Endurance, which tolerates constant rewriting; an ordinary card wears out in a camera within months. For a phone where the card will serve as internal storage, choose class A2.
