This is like putting an SSD on your Raspberry PI 3/3+ or similar embedded device. Read IO's 2500/second- will saturate the SD Card interface of any device it is put in. Make sure, though, that your device is capable of that many IOPs in order to take advantage of it. Some devices aren't that robust- so an A1 or even just an ordinary card will do.
Cameras are iffy for an A2 rated card. Smartphones, tablets, embedded computers, however...are quite capable of using it to the fullest possible. You should know a bit of something of what your device is capable before buying this class of part, expecting amazing things out of it. It's an, "It depends..." type thing. My application is thoroughly unleashed. My phone was. My tablet was.
