Understanding Micro SD Cards

Capacity and Storage Needs

When selecting a micro SD card for your dash cam, consider the storage capacity. Dash cams continuously record and overwrite old footage, so a larger capacity allows for more extended recording periods before data is overwritten. Typical capacities range from 32GB to 256GB. The choice depends on how much footage you want to retain and the resolution at which your dash cam records. Higher resolutions, such as 4K, require more storage space compared to 1080p.

Speed Class Ratings

Speed class ratings indicate the minimum write speeds of micro SD cards. For dash cams, consistent write speeds are crucial to ensure smooth recording without frame drops or interruptions. There are different classes, including Class 10, UHS Speed Class 1 (U1), and UHS Speed Class 3 (U3). For most dash cams, a Class 10 or U1 card is sufficient, but for 4K recording, a U3 card is recommended.

Endurance and Durability

Dash cams operate in harsh conditions, from extreme temperatures to constant vibration and power cycling. An endurance-rated micro SD card is designed to withstand these conditions, ensuring reliability and longevity. These cards are built with high-quality NAND flash memory and are tested for durability, making them ideal for continuous recording applications like dash cams.

Compatibility

Ensure that the micro SD card you choose is compatible with your dash cam. Check the dash cam’s user manual for supported card types and maximum capacity limits. Most modern dash cams support micro SD cards up to 128GB or 256GB, but older models might have lower capacity limits.
