BUYING GUIDE
Why Dashcams Need Endurance SD Cards
Dashcams write and overwrite continuously, 24/7 if parked recording is enabled. Standard SD cards are designed for occasional writes and will fail within months under this workload. Endurance cards use different flash memory cells (MLC or pMLC) rated for hundreds of thousands of write cycles. Always use a high-endurance card in a dashcam to avoid losing crucial footage.
