Buying Guide
What capacity should you choose for a dash cam card? For most daily driving use, 64GB is sufficient for several hours of footage, while 128GB or higher is better for long trips or multiple cameras. If you frequently pull footage to a computer, higher read speeds help with faster offloading. Choose cards with UHS-I, U3, or A1 ratings to ensure smooth video capture and app performance.
What speeds matter for dash cams? Read speed affects how quickly you can access and back up footage, while write speed influences ongoing recording without dropped frames. For 1080P recording, U1/A1 cards with sustained write performance are typically adequate; for 2.7K–4K or extended recording, prefer U3 and higher sustained write speeds.
Durability and compatibility should not be overlooked. Look for cards that are water, shock, X-ray, and temperature resistant. An SD adapter is useful for transferring files to a computer or phone. Ensure your dash cam supports the card’s format and capacity to avoid compatibility issues.
Formatting and maintenance tips. Use the dash cam’s recommended file system (often exFAT). Regularly format the card after backing up important footage. Keep extra cards on hand to avoid gaps during trips or extended surveillance periods.
