Frequently Asked Questions
What sustained write speed do I need for 4K action camera recording?
Most 4K60 recordings are fine on V30 (30 MB/s sustained) cards, but for 4K120, high-bitrate codecs or RAW video choose V60 or V90 rated cards. Check your camera’s recommended card class and prioritize sustained write spec over peak read numbers.
Are multi-pack cards (5-pack/3-pack) safe to use for 4K video?
Multi-packs are convenient and often good value, but verify each card’s UHS/V-class rating. Some budget multi-packs are better suited to backups or Full HD rather than sustained high-bitrate 4K. For critical shoots, use rated V30+ cards and rotate cards frequently.
How should I care for and format memory cards for best reliability?
Always format cards in the camera before first use, avoid filling them to absolute capacity for long continuous shooting, use multiple cards instead of overwriting one, safely offload footage via a fast reader, and store cards in protective cases. Regularly back up footage to two separate drives.
