Speed badges sell cards; the workload decides which one survives. Pick your use case below for the right grade and speed class — and skip the ratings you're being upsold.
These cameras overwrite around the clock. A consumer card wears out in months and fails silently — you find out when the footage isn't there. Endurance, not speed badges, is what keeps it recording.
Light, occasional writes — so capacity and value matter more than endurance. This is the one place the A1/A2 app-performance rating actually earns its keep, because the card runs apps and loads files.
Short, intense high-bitrate bursts need sustained write headroom, not just a fast label. Counterfeit and over-spec'd cards are rampant here — and the footage you lose is unrepeatable, so verify capacity before the shoot.
