Look at the bitrate
Two 4K modes can produce very different sizes. The bitrate determines how much data should be written each second and how much fits on the card.
Minimum speed
Check the class recommended by the manufacturer. A flashy maximum read is no substitute for sustained write speed.
Bring a second unit
A small, reliable reserve card does more than a single huge card doubled as a permanent file.
DroneBase Checklist
This guide is only useful if it results in a verifiable decision. Before closing the purchase, preparing the equipment or taking off, make sure you can confirm each of these points with the manufacturer's documentation, the actual state of the material and the specific conditions of the operation.
- Maximum bitrate.
- Speed class.
- Compatible capacity.
- Expected recording time.
- Reservation card.
- Verified copy.
If one of the data is missing or depends on the variant, treat it as pending. Don't replace a missing specification with a trade promise or a zone check with an old capture. The correct decision is the one that remains valid when the pack, environment or flight plan changes.
What should you be able to answer when you finish?
Which information is official and which is only indicative? What condition can change the result? What check should you repeat just before using the drone? If the three answers are clear, the guide has fulfilled its function: reducing uncertainty without pretending that all flights and all products are the same.
The DroneBase RuleIf a decision depends on the specific location, the marking of the drone or the type of operation, always confirm the case with CAA and CAA airspace alerting guidance before taking off.
