Overview
A dash cam or body cam that records all day is where this endurance card belongs. It is built to survive constant overwriting of old footage, and an adapter is included for full-size SD slots.
The reason to buy is endurance: a rated recording life measured in tens of thousands of hours, with a five-year warranty. The limit is the speed, which suits Full HD security footage more than high-bitrate 4K or burst photography.
Who it's for
Cameras that record continuously, such as dash cams and home security units, benefit from the endurance rating. Photographers, drone pilots and phone users who want quick file transfers should look at a faster card.
Pros and cons
- Rated for very long recording life
- Five year manufacturer warranty
- Proofed against water, magnets and X-rays
- SD adapter included
- Speeds are modest
- Video class stated two ways
- Adapter warranty is shorter
- Not for burst photography
Performance notes
The rated recording hours assume Full HD video at a fixed bitrate, so real life varies with camera settings and the camera's battery. Sustained write speed sets whether footage records without gaps, and endurance means the flash can be rewritten many times.
