Card speed
Driving recorders require that memory cards to be at least a class10 high-speed memory card. Class10 only represents reading speed, but the recorder requres the writing speed of the card. What’s more, the speed of recorders is changing each passing day as well as many of them support 4K recording. In fact, a memory card with a higher writing speed should be used.
| symbol | Minimum write speed of serial data | SD bus mode | recommanded usage | |
UHS Speed Level | 30MB/s | UHS-II UHS-I | 4K 2K video recording | |
| 10MB/s | Full-HD video recording continuous shooting, Full-HD static photo | |||
Speed Class | 10MB/s | High Speed (HS) | ||
| 6MB/s | Normal Speed (NS) | HD or Full-HD video shooting | ||

| 2MB/s | normal video shooting |

The capacity of memory card for dash cam
This depends on the user manual of the driving recorder: what kind of card can be equipped, how large the card can be are all explained in there. As long as the size does not exceed the carrying capacity of the equipment, you can choose according to your actual situation. However, if you want to save the entire video on a self-driving tour, it would be a problem if the capacity is too small. Even the loop video can only save about one and a half hours of video. Once a traffic accident requires evidence collection, there may be data loss. So, try to buy a memory card with a larger memory.
The quality of memory card for dash cam
Due to the complicated driving conditions of many car owners, the jitter can easily cause the recorder some issues. For instance, it will be too hot, unable to store, unable to record, crash and black screen, and may even burn the driving recordder directly. It is said that the smaller the capacity, the easier it is to break. As long as you drive, the memory card will be written and erased continuously. While the number of erasing and writing of a consumer-level memory card is only 300, frequent card replacement has become a headache for many drivers. In addition, consumer-grade memory cards do not have a life reminder function. Also, car owners have no idea when their card should be replaced. What’s more, once the number of erasing and writing is used up, data loss is extremely likely to occur. Furthermore, bad weather can easily cause damage to the memory card, so it is particularly important to ensure the quality when purchasing a memory card. MTR3C Industrial Storage↓↓↓
