So I been having intermittent issues with my dash cam over the last year, it finally seemed that the problem was the memory card. Now looking further into it, the issue at hand is that most memory cards aren't suitable for the 24/7 continous writing in surveillance/CCTV mode enabled dash cams. A typical 32GB card will hold maybe 2, maybe 4 to 5, hours worth of content which means that it is probably eating through its entire capacity's worth perhaps 2 or 3 times a day. Most common memory cards are built on a cheaper variety of memory chips called TLC NAND, which have relatively short write endurance of around 3,000~5,000 cycles, which apparently translates to about 150~300 total overwrites. Examples include be SanDisk Ultra cards... Then there's MLC and SLC NAND, which without going into working detail, get more endurance. Doing some simple math, 150 total overwrites, assuming the card does it twice a day, a cheap memory card could eat through its entire rated write endurance in less than a year! My older dashcam-used memory cards, even with formatting, cuck up the camera every few seconds now. Anyway, I notice now there are High Endurance for video surveillance memory cards by SanDisk, Lexar and Transcend, advertised to handle at least 2 years of continuous recording. I'm trying out the SanDisk card, will be interesting to see if it's still problem free after warranty is over. Anyone else tried those, or other brands of cards? I'd also like to get some more data from other users about how long their memory cards are lasting in cams.
