Best picks
SanDisk MAX Endurance is our first choice for demanding loop recording, while Samsung PRO Endurance offers broad capacities and VIOFO owners should first check their camera's approved-card guidance. Kingston and Lexar provide practical endurance alternatives.
Quick answer
The best SD card for a dash cam is an endurance model that your camera maker supports. SanDisk MAX Endurance leads for its stated continuous-recording endurance, Samsung PRO Endurance is a strong all-round option, and SanDisk High Endurance offers capacities up to 512 GB. Kingston High-Endurance and Lexar High-Endurance are worth considering when their capacity and speed class match your recorder.

Common questions
Choose a capacity within the camera's stated range. Higher-resolution and multi-channel cameras fill a card faster, but an unsupported large card is not an upgrade.
It is the safer choice because loop recording repeatedly writes and overwrites data. Standard cards may not be designed or warranted for that workload.
Use the class required by the camera maker. High-bitrate 4K or multi-channel models often specify U3 or V30, while some Full HD cameras accept a lower class.
Follow the interval in the camera manual or its on-screen reminder. Format in the camera after saving important clips, and replace the card if errors return.
Keep exploring
Start with the coverage you need: front-only, front and rear, cabin or a wider multi-camera view. Then compare recording detail, storage and power requirements.
VIOFO A229 Pro 2CH is our broad recommendation for detailed front and rear coverage. Garmin Mini 3 favors discretion, while Garmin X310 is the sharper single-camera choice.
The A329S serves buyers seeking high-detail multichannel recording; A229 models cover more moderate dual-camera needs, while A119 Mini 2 is the compact front-only option.
A front and rear dash cam records both directions and can provide context a single lens misses. Check the rear-camera cable route and simultaneous recording resolution before buying.
