SanDisk High Endurance review: 20,000 hours of testing later, it's the microSD card to beat

**Executive summary:** ZDNET conducted a three-year continuous recording test of SanDisk High Endurance 256GB microSDXC cards in dash cams and found they surpassed the rated 20,000-hour lifespan (running ~26,500 hours), wrote an estimated 24 TB of data, maintained original performance, and showed no errors, leading to a recommendation of the High Endurance line for continuous recording and suggesting Max Endurance for even longer deployments.
