What is the difference between a high endurance card and a regular micro SD card?
Dash cams write video continuously, which wears out ordinary cards quickly. High endurance cards use pSLC-mode flash engineered for substantially higher program/erase resilience per block, giving a much longer service life under constant loop recording.
The 64GB and 128GB versions are microSDXC cards. microSDHC only covers capacities up to 32GB.
Yes. It is rated for operation from -20 °C to 70 °C, covering the interior temperatures a parked or running vehicle can reach.
Class 10 is the baseline for 4K dash cam recording. U3 guarantees a minimum sustained write speed of 30 MB/s, giving more headroom on high-bitrate 4K systems.
UHS-II offers no benefit here, since dash cam hardware runs at UHS-I speeds.
