What is the appropriate size for a dash cam memory card?

It is recommended to use a 16GB or 32GB memory card for dash cams. Here are the relevant details: 1. Different choices: You can select different memory card sizes for your dash cam based on your driving duration to avoid insufficient memory capacity during usage, which may affect performance and compromise driving safety. 2. Video quality: When choosing a memory card for a dash cam, the first consideration should be the video quality of the recorder. Most recorders on the market support 720p and 1080p resolutions, with 1080p videos occupying nearly twice the space of 720p videos.
I've been into road trips for the past few years and have gone through several dash cams. For regular commuting, 32GB is actually sufficient, recording about 4 hours at 1080P resolution. But! During holidays when stuck on the highway for seven or eight hours, the capacity just can't keep up. Nowadays, dash cams have upgraded to 2K resolution, and 64GB is barely enough. I later switched to a 128GB high-speed card, which can store videos from cross-province trips covering three provinces. Remember to buy a U3-rated card for faster transfer speeds, or 4K videos will lag like a slideshow. Also, a heads-up: the bigger the card, the more important it is to back up. Last time on the Sichuan-Tibet route, I almost missed the stunning golden mountain sunrise because the card was full halfway through recording.
