Best picks
The best SD card for a dash cam is built for constant rewriting, not occasional phone use. SanDisk MAX ENDURANCE is our top pick, with Samsung PRO Endurance close behind for high-capacity recording.
Quick answer
SanDisk MAX ENDURANCE is the strongest all-round choice because its published endurance figures lead this shortlist. Samsung PRO Endurance is a compelling high-capacity alternative, Kingston High Endurance suits buyers who want a simpler range, and a Nextbase card is the safest match for a compatible Nextbase camera.

Best overall
Drawback: Its maximum listed capacity is 256GB, so it will not suit cameras that support larger cards and need very long retention.

Best high-capacity endurance option
Drawback: The headline endurance figure is tied to Full HD footage at Samsung's specified bitrate, so real retention varies with the camera and resolution.
Best straightforward endurance card
Drawback: The capacity range stops at 128GB, which can mean a shorter recording window in high-resolution multi-camera systems.

Best for a broad choice of capacities
Drawback: Its published endurance at each capacity is lower than the corresponding MAX ENDURANCE range.

Best for compatible Nextbase dash cams
Drawback: Its main advantage is brand compatibility rather than class-leading published endurance data.

Common questions
Choose a high-endurance microSD card that your dash cam maker lists as compatible. SanDisk MAX ENDURANCE is our leading all-round pick, but the correct capacity and format for your exact camera matter more than buying the largest card.
Yes, high-endurance cards are the sensible choice because a dash cam continuously writes, deletes and rewrites video. Ordinary cards may be fast enough but are not necessarily designed for that sustained workload.
Use a capacity explicitly supported by your dash cam. Larger cards retain more footage before loop recording overwrites older files, but an unsupported capacity may fail to format or record reliably.
No. The card must meet the camera's sustained write-speed requirement, but endurance and compatibility are just as important as headline speed. A fast general-purpose card can still be a poor choice for constant rewriting.
Follow the schedule in your dash cam manual and format the card in the camera when instructed. Back up any footage you need first, because formatting erases stored recordings.
Keep exploring
Start with the coverage you need: a discreet front camera for the road ahead, or a front-and-rear system for evidence from both directions. Our guides then narrow the choice by installation, connectivity and brand.
The Nextbase 622GW is our balanced UK pick for its detailed recording, stabilisation and accessible touchscreen. Garmin Mini 3 suits a discreet fit, while VIOFO A329S covers the front and rear at high resolution.
A dual-camera kit is the direct choice when you want the road ahead and traffic behind in the same recording system. Check rear resolution and cable length, not just the headline front-camera specification.
The 622GW has the strongest recording specification in this trio; the 522GW keeps the large touchscreen and polarising filter at 2K, while the 322GW covers the essentials.
