Won't work in the new Switch.

High endurance are designed to be written to repeatedly, ideal for something like a camera where there are constantly new files being written. In my experience, non-high endurance cards fail much sooner if you try to use them in a security camera or similar.

Quote from HexiumVII :
These are probably TLC flash with 300 cycles on the lower end. So you can get maybe 150TB writes with this card. You can extrapolate this with a 256gb card only doing 75tbw. Depending on how much you drive and how big the video is you can figure out how long it will last. I dont drive that much so 64GB regular card has lasted me 5 years so far. Endurance cards are probably mlc and have 3-10x the endurance of tlc. We might see qlc cards soon which will probably cut the endurance by 1/3 , but will see them in larger 1tb+ cards.
Sadly none of the normal endurance cards are "mlc".
They are all tlc or qlc.

Hmm. These things are getting cheap enough and fast enough that they might be a good choice for a backup drive that I leave plugged in. Yeah, I know it isn't high endurance, but as a backup drive on a personal computer, it would easily last a few years. Seems like cheap insurance.

People not reccommending this for a dash cam need to keep in mind how large it is. Because of the large size, it will take a long time for a dash cam to fill it, which means it's life will be extended. Might not be a good choice for someone that drives for a living, but for the average person, this would last a long time and have the added benefit of being able to store a lot of footage without over writing itself.
