Review on 📱 SAMSUNG 256GB MicroSD Evo Memory Card with Adapter - 100MB/s UHS-3 (MB-MP256GA/AM) by Mike Quade

. I confirm that I am an active user as I am a carsharing driver. I bought 4 of the 64GB which I swap out every 4 hours as needed in my dash cam depending on how many hours I drive each day. This card 1 was the most used in my DVR. Today it no longer shows up on my dashcam or laptop. I tried everything, but as if the card is not inserted. Now I'm worried that the other 3 will start dying. Sent an email to support today. I think I'll find out that they stand behind their 10 year guarantee. In the meantime I've already ordered a 128GB version to replace the dead 64GB version as my new DVR can use bigger cards so I don't have to switch as often. I just hope the rest of my cards don't suddenly start dying.
