What type of memory card should be used for a dash cam?
4 Answers
Dash cams generally use TF cards, and as long as the speed reaches C6 or above, they are usually compatible. Considering the convenience of inserting and removing the card, the memory card slot in dash cams is designed to be easily accessible. Typically, the memory card slot is located on the side of the device, though the exact position may vary depending on the product model and type. More details are as follows: 1. For rearview mirror dash cams, the memory card slot is usually located on the upper side of the device. For hidden or smaller dash cams, the slot is generally found on either side of the device. 2. Some dash cams may have a more compact design, with the memory card slot covered or concealed, but it is still positioned on the side of the device. This should not be a major issue, as the device is relatively small, and a careful search will easily locate it.
When it comes to the memory card for a dash cam, I've found that choosing the right one is crucial. With over a decade of driving experience and having used various cards, I now exclusively use high-speed microSD cards. It's best to opt for 64GB or 128GB capacity because high-definition videos can fill up several GBs in just one day. Pay close attention to the speed class—only Class 10 or UHS-I Class 10 and above will ensure smooth recording without lag. I've tried endurance versions like SanDisk High Endurance or Samsung PRO Endurance, which are designed to withstand high temperatures and vibrations, making them exceptionally durable. Don’t cheap out with regular cards—if they fail at a critical moment and you lose the footage, it can be disastrous. I also format the card every two months to maintain stable performance. This gives me peace of mind while driving, knowing the dash cam runs smoothly and I’m prepared for any unexpected incidents.
When I first installed a dash cam, I made a mistake by buying a cheap 32GB memory card at random. It started malfunctioning within days, with videos being choppy and automatically deleted. Later, I learned that dash cams require specialized endurance cards—small capacity can't handle continuous video recording, and slow speeds cause dropped frames. Now, I use a 128GB card from high-end series like Kingston or SanDisk, specifically designed for continuous recording, which is much more durable. When choosing a card, make sure the write speed is at least 100MB/s, stick to reputable brands, and avoid counterfeit products online. Develop a habit of using the dash cam's built-in formatting function to clear the card monthly for a longer lifespan. Driving safety is crucial, and a reliable memory card ensures complete recordings—otherwise, the device is wasted.
The key factors for a dashcam's memory card are speed and capacity. Based on my years of experience with microSD cards, I recommend starting with at least 64GB, with 128GB being even better, given how large video files can be. Speed is crucial—opt for V30 or A2-rated cards for stable writing to avoid lag or file corruption. Regular cards tend to fail when overheated, which is why I prefer endurance models like the SanDisk High Endurance, which are shock-resistant and support loop recording. Don’t skimp on this expense, or you might end up with blank footage when it matters most. A quick weekly check of the card’s status ensures everything runs smoothly, keeping your device reliable and trouble-free.
