SAMSUNG PRO Ultimate microSD Memory Card + Adapter, 256GB microSDXC, Up to 200 MB/s, 4K UHD, UHS-I, Class 10, U3,V30, A2 for Action Cam, Drone, Gaming, Phones, Tablets, MB-MY128SA/CA [Canada Version] Got this for my gopro hero mini. Works just fine but little bit dubious about the claimed 200MB/sec read speed and 130MB/Sec write speed on my card reader. And yes my card reader isnt the bottle neck since i test much faster cards than this on the same usb port and usb reader. Nevertheless it works for my needs and it is a cost effective bargain with a good name brand that has a good reputation with SSD/NVME's too.

Loads of games saved!!! Perfect
