I read all the bad press on Sandisk, but mine haven't had issue. I recently had a 32gb top rated Lexar standard SD fail and one of my 32gb transcend class 10 micro sd cards fail.
Unlike my cameras, when my dashcams have issues, I can't tell if the card or dashcam. I'm thinking best to check once a while and have a known operable spare for swap and testing.
I have been using a 256GB Sandisk without any problems at all for close to 3 months now . Kind of pricey, but I wanted a lot of history available on the chip if needed. The exact designation of my chip is "SanDisk Ultra 256GB MicroSDXC UHS-I" It remains to be seen how it performs during the heat of summer!
Is it a card that looks like this?
With the latest firmwares and highest video quality these cards doesn't work well. I've tried the 64GB version and the black version (128GB) and the dashcam kept restarting constantly.
What firmware are you using, and what video quality setting?
It performs FAR FAR better than the 128GB PNY chip that came with the camera which had repeated hard failures!
I've been using the Lexar 633x 64GB with zero problems for 6 months.
saw plenty of recommendations for this brand so we got it. 64gb - running fine so far - 3 weeksLexars are probably fine too.......snip.....
