Frequently asked questions
- Which memory card format do I need?
- Devices accept specific formats such as SD, microSD or faster professional types, so check your manual before buying. Using the wrong format means the card will not fit or work.
- What do the speed ratings mean?
- Speed class and related ratings indicate the minimum sustained write speed, which matters most for continuous video and rapid bursts. Match the rating to what your device requires.
- Is a bigger card always better?
- Larger capacity stores more, but spreading footage across a few cards limits how much you lose if one fails. Balance convenience against that risk for important shoots.
