When buying a dash cam, one of the first questions drivers ask is: What size SD card do I need? The memory card you choose determines how long your dash cam can record before looping over old footage. A 64GB micro SD card for dash cam use is a popular mid-range option—offering more storage than a 32GB card while remaining affordable and widely supported. But is it the right choice for you? Let’s find out.
64GB Micro SD Card for Dash Cam
Why a Micro SD Card Is Essential for Dash Cams
Dash cams don’t come with built-in storage. Instead, they rely on micro SD cards to capture and save every trip, from daily commutes to long road trips. Since dash cams record continuously in a loop, the card must be durable, high-endurance, and fast enough to handle nonstop writing and rewriting of video files.
That’s why choosing the right micro SD card size for dash cam matters.
How Long Does a 64GB Micro SD Card Record?
The recording time depends on your dash cam’s resolution and settings. On average, here’s what you can expect from a 64GB micro SD card for dash cam recording:
- 1080p Full HD (standard): 8–12 hours of continuous footage
- 1440p (2K): 6–8 hours of footage
- 2160p (4K): 4–6 hours of footage
After the card fills up, the dash cam automatically overwrites the oldest files with new recordings (known as loop recording).
This makes 64GB cards a sweet spot—large enough for long trips but still affordable.
Is 64GB Enough for a Dash Cam?
Yes, for most drivers, a 64GB micro SD card is enough. It works well if you:
- Want to store a full day of driving without worrying about overwriting too soon.
- Use 1080p or 2K resolution (4K users may prefer 128GB or higher).
- Regularly transfer or back up important clips.
If you’re a professional driver (e.g., Uber, taxi, or delivery), or you record in 4K ultra HD, you might benefit from upgrading to 128GB or 256GB (if your dash cam supports larger cards).
Best Types of 64GB Micro SD Cards for Dash Cam Use
Not every micro SD card is suitable for dash cams. Standard cards can wear out quickly due to constant looping. Instead, choose high endurance micro SD cards designed for dash cam and surveillance use.
Look for:
- Class 10, UHS-I/U3 speed rating (for smooth video recording).
- High Endurance or Pro Endurance models (optimized for constant rewriting).
- Temperature resistance to handle heat and cold inside a car.

- Format monthly inside the dash cam.
- Avoid fake cards—buy only from trusted retailers.
- Replace every 12–24 months, depending on use.
- Check compatibility with your dash cam before purchase.
