A dash cam is only as reliable as the memory card it records onto. While microSD cards may seem like a small accessory, they play a critical role in ensuring your dash cam captures and stores footage without errors. However, not every microSD card is built to handle the demands of continuous dash cam recording.

What memory card is recommended for a VIOFO dashcam?
If you’re using a VIOFO dash cam, here are the key factors to consider before choosing the right SD card.
1. Storage Capacity
The capacity of your microSD card determines how much footage your dash cam can store before it begins looping over older files.
- Minimum size: 64GB is the entry-level recommendation for most dash cams.
- For daily use: 128GB or 256GB cards are ideal, especially if you drive long distances or need extended recording time.
- For heavy users: Some VIOFO dash cams can even support 512GB cards, making them perfect for commercial drivers or long road trips.
2. Write Speed
Dash cams write video files constantly, so speed matters.
- Class 10 or U1: Suitable for standard Full HD recording.
- U3 or higher: Strongly recommended for 4K dash cams to ensure smooth recording without dropped frames or corruption.
A higher write speed means your dash cam saves footage instantly and reliably, even during demanding conditions.
3. Endurance Rating
Unlike cameras or smartphones, dash cams record in a continuous loop, which means the memory card is under constant stress. Ordinary cards wear out quickly, leading to errors or lost files.
That’s why you need a high-endurance card built for heavy read/write cycles. These cards are designed to:
- Handle constant recording without corruption.
- Withstand extreme temperatures inside vehicles.
- Resist shock and vibration while driving.
4. Compatibility
Not every SD card works seamlessly with every dash cam. Before purchasing, always check your dash cam’s specifications for supported card types and maximum capacity. Using an incompatible card can result in failed recordings or even card damage.
5. Brand, Warranty & Price
When it comes to memory cards, brand reputation matters. Cheap, generic cards often fail early, risking your footage. Instead, choose cards from trusted brands known for durability and reliability.
- Warranty: Look for at least a 12-month warranty (VIOFO’s own cards include this as standard).
- Price vs. value: While budget cards may look tempting, investing in a premium card saves money in the long run by avoiding failures and lost recordings.
Recommended Cards for VIOFO Dash Cams
After extensive testing and feedback, VIOFO officially recommends:
- VIOFO Original microSD Cards – Optimized for dash cam use, high endurance, and reliable performance.
- SanDisk MAX Endurance Cards – Proven durability and consistent recording quality.
⚠️ Avoid cards such as the Samsung EVO series, as they are not designed for the constant recording demands of dash cams.
Final Thoughts
Choosing the right microSD card is just as important as selecting the dash cam itself. A poor-quality card can result in corrupted files, lost evidence, or even device malfunction. By opting for VIOFO Original or SanDisk MAX Endurance cards, you’ll ensure reliable, long-lasting performance for your dash cam.
Your dash cam protects you on the road—make sure your memory card is just as dependable.
