Is 16GB Enough for a Dash Cam?
2 Answers
16GB is sufficient for a dash cam as long as you regularly clean up the memory. However, to avoid unnecessary trouble, it is recommended to purchase a dash cam with 32GB or 64GB storage. Dash cams save recorded footage in segments of 5 or 10 minutes. If the stored data is not cleaned up periodically, over time the video data will occupy the entire memory, preventing new video data from being saved properly. Therefore, it should be cleaned up once a month. When purchasing a dash cam, you can opt for one with larger storage capacity, which allows for storing more video data. On one hand, this saves the car owner the hassle of manually cleaning up the data; on the other hand, it ensures the quality of the video data, playing a decisive role in critical moments.
As a seasoned driver with ten years of experience, I've tested quite a few dash cams. A 16GB card can only store about 90 minutes of 1080P video before it's full, and hearing the 'memory card full' alert at every red light is truly annoying. Especially on long trips, before you even reach the service area, critical footage of an accident ahead might get overwritten. Now I've switched to a 64GB card, which can store up to 6 hours of video. Whether it's someone cutting in or an accident, I can even retrieve footage from three days ago without any issues. I recommend new car owners start with at least a 32GB card—spending an extra twenty or thirty bucks saves a lot of hassle. After all, it's just like skipping two cups of milk tea.
