I have always loved Sandisk products. I choose to populate my 9 security cameras with the 128GB Ultra Micro SD cards. Well I made a mistake. Six of the nine Micro SD cards failed last week. Weird !! Well, it turns out that Sandisk does not warranty this retail card in security cameras. I purchased from Amazon I read everything included in the product description and I don't remember seeing not to use in security cameras. Sure enough it does say that on the warranty page on their website now. Anyway the cards are 8 months old and are bricked due to a limited number of writes.
My name is Zack from SanDisk® Support. I regret to learn that you are facing issues with the memory card. Please note that we do not recommend our Ultra cards to be used with devices with constant read and write operations like Dashcams, video monitoring, security and surveillance devices Internet protocol/network cameras, and in-car recording devices.
We would recommend you considering our High Endurance cards for the above applications. To know more about our high endurance cards refer to the link below: - https://www.sandisk.com/content/sandisk-main/en_us/home/memory-cards/microsd-cards/high-endurance-microsd.html
