Official Generic 4K Dash Cam SD Card Requirements
-
Format: microSD (sometimes full SD)
-
Minimum Speed: V30 (30 MB/s write)
-
Maximum Capacity: Up to 256GB
Why these requirements? 4K dash cams write about 50 to 100 Mbps depending on the model and codec. V30 guarantees 30 MB/s sustained, above that rate. Loop recording rewrites the whole card over and over, so high-endurance cards, which manufacturers rate in recording hours, outlast standard cards.

Frequently Asked Questions
What SD Card Do I Need for Generic 4K Dash Cam?
The Generic 4K Dash Cam takes a microSD (sometimes full SD) card rated V30 or faster. 64GB or 128GB covers most owners, and the maximum is 256GB. Buy SanDisk, Lexar, Samsung or Kingston from a reputable seller: counterfeit cards are the most common cause of lost files.
What's the difference between dash cam and regular microSD cards?
Endurance. High-endurance cards are rated for tens of thousands of hours of continuous recording; SanDisk rates its MAX Endurance line at up to 120,000 hours. Standard cards carry no such rating.
Can I use a regular fast microSD card in a dash cam?
It works, but wears out sooner. Speed doesn't help with constant rewrites. A high-endurance card is the better buy.
Is 64GB or 128GB better for a dash cam?
128GB for most drivers. At 4K, 64GB holds roughly 1.5 to 3 hours and 128GB about double. For parking mode, buy 256GB.
Is V30 required for Generic 4K Dash Cam?
Yes. V30 guarantees 30 MB/s of sustained write, which keeps the Generic 4K Dash Cam free of dropped frames, clips that stop early, or corrupted files. Faster cards work too.
What size SD card should I get for Generic 4K Dash Cam?
64GB covers light use; 128GB suits heavy use. The maximum is 256GB.
Can I use older or slower cards with Generic 4K Dash Cam?
Not below V30. Slower cards cause dropped frames, clips that stop early, or corrupted files. Check the card label for the V30 mark.
Does the brand matter for Generic 4K Dash Cam?
Yes. SanDisk, Lexar, Samsung and Kingston cards meet their rated speeds. Buy from the brand's store or a major retailer: counterfeit cards sold under those names are common on marketplaces.
What happens if I use the wrong card with Generic 4K Dash Cam?
A card slower than V30 causes dropped frames, clips that stop early, or corrupted files. A card over the maximum capacity or in the wrong format may not be recognized.
How long will an SD card last in Generic 4K Dash Cam?
It depends on write volume. Constant loop recording wears cards out, which is why high-endurance cards are rated in recording hours. Replace the card at the first error message.
