I use the card to transfer data (photos) between my computers and processing steps to save between (hence the 128GB). I must say with a USB3.0 stick works that super fast and I also have had no failures. For large video the card reaches the speed of the SSD and therefore I work partly on the map. To take pictures with no backup would be me too "exotic" (size and manufacturer), but if the part will continue as positively, simple and absolutely flawlessly working it is "promoted" into the camera.
