We've had zero issues since testing the A1 in January of this year. Just a recommendation as this has worked for our staff and customers.Sandisk A1 is a very fast card (useless feature since peak write rate of DR750s-2CH is less than 10MB/s for extreme quality mode!), not a card recommended or warrantied for dashcam use. I highly recommend endurance cards for dashcam use especially if intended dor 24/7 recording.
I've seen the warranty verbiage that specifically states that certain SD cards are not to be used in a dash camera. But, how would they be able to tell? How are they going to decipher if a failed sd card was used in a dash camera or a GoPro recording at 4k or a cellphone recording at 4k? I'm just playing devil's advocate here.More important to understand the reason why they void warranty and have warranty on Pro Endurance and High Endurance cards , this ain't no marketing gimmick !
