Why Your Dash Cam Needs a High-Endurance SD Card
It is tempting to reuse a spare phone card, but dash cams put a unique strain on storage. High-endurance cards exist for exactly this reason.
Constant overwriting
Loop recording rewrites the same card all day, every day. Standard cards are rated for far fewer write cycles and wear out quickly under this load.
Silent failure is the risk
A worn card can appear to work while quietly failing to save clips, so you only discover the problem when you need footage that was never recorded.
The fix is cheap
A high-endurance card costs a little more and is engineered for continuous writing. It is inexpensive insurance against the one moment that matters.
What to buy instead
See Best microSD Cards for Dash Cams for what to look for, or the SanDisk 128GB High Endurance card we cover directly.
Frequently asked questions
How do I know if my SD card is failing?
Warning signs include recording gaps, files that will not play, or the camera reporting a card error. If in doubt, replace it — a failing card can appear to work while quietly missing recordings.
