Samsung PRO Endurance microSD Memory Card with Adapter, Up to 100MB/s Read, 32GB–256GB

Built for surveillance duty — continuous loop recording in security cameras, dashcams and body cams, where an ordinary card degrades within a year. Samsung publishes a rated recording-hours figure that rises sharply with capacity, so buying larger buys service life as well as storage.

The video speed class is not the same at every capacity in this line; the smallest one is rated lower, which constrains 4K. Check the variant before ordering.
