The SanDisk High Endurance microSD card is built for devices that write constantly: dash cams, home security cameras and body cams. SanDisk rates it for up to 40,000 hours of recording, far beyond what a standard card is designed to handle, and it is tested to survive heat, cold, shock and water. It suits anyone who needs footage to keep recording without the card failing early. Against regular microSD cards it trades peak speed for write endurance, so it is the safer pick for loop recording rather than for action cameras or fast file transfers.

Owners generally report the card holding up well in dash cams and security cameras, with footage intact after long periods of loop recording. Complaints tend to focus on speed and on cards failing sooner than the endurance rating suggests.
The SanDisk High Endurance microSD card is made for devices that record continuously, such as dash cams, home monitoring and security systems. It is built for continuous rewrite cycles and offers up to 40,000 hours of recording time. Total hours will be less when recording in 4K UHD.
