What is the difference between a high-speed card and a regular card for a dash cam?
2 Answers
The difference between a high-speed card and a regular card for a dash cam lies in their read speeds. Below is an introduction to dash cams: The function of a dash cam: A dash cam is a device that records images, sounds, and related information during vehicle travel. After installing a dash cam, it can record the entire driving process in video and audio, providing evidence in case of traffic accidents. For those who enjoy road trips, it can also be used to document the journey through challenging terrains. Precautions when using a dash cam: The video footage recorded by a dash cam must not be edited. If edited, it may not be helpful in the event of an accident. This also serves as a precaution against unavoidable fraudulent claims in today's society.
The biggest difference between high-speed cards and regular cards for dash cams is the read and write speed. I usually prefer recording in 4K resolution while driving, and only high-speed cards with fast enough write speeds can ensure smooth video playback without dropped frames. Regular cards often miss crucial footage when recording in high definition. Additionally, high-speed cards are much more durable than regular ones. A regular card might wear out after just a few months, while high-speed cards are far more resistant to high temperatures and frequent read-write cycles. I've used regular cards before, and during summer when the car was parked under the sun, the card overheated and failed. However, high-speed cards can withstand continuous operation in high temperatures. Although high-speed cards are a bit more expensive, considering the importance of preserving critical driving data, it's worth investing in them for peace of mind—they won't let you down when it matters most. When buying a card, remember to check the UHS speed rating; U3 or V30 are both suitable options.
