Buying Guide
What to consider when choosing a CFast 2.0 memory card:
- Capacity needs: Assess your typical shoot length, bitrate, and backup workflow. Larger capacities reduce card swaps but come with bigger physical cards.
- Read vs. write speeds: For smooth recording, prioritize higher write speeds to handle high-bitrate codecs and 4K/6K RAW. Read speeds matter for faster offload and media management.
- Endurance and reliability: Professional cinema work benefits from robust NAND technology and endurance. Consider cards designed for sustained write performance.
- Camera compatibility: Ensure your camera or recorder supports CFast 2.0 and can utilize the card’s maximum speeds. Some cameras limit write speed regardless of card capability.
- Form factor and durability: Look for cards with sturdy housings and reliable connectors, especially for on-location shoots or Extreme environments.
- Warranty and support: While not a hands-on test, consider brands with clear support policies and warranties.
