Kingston Canvas Go! Plus SD Memory Card, Up to 170MB/s Read, UHS-I, 64GB–1TB

U3 and V30 put this at the sensible floor for 4K in a UHS-I body, and it is the cheaper sibling of the Kingston Canvas Go Plus SDXC Memory Card Gen4 200MB/s C10 UHS-I U3.

The 170MB/s in the title is read speed; it shortens the copy off the card and nothing else. Write speed decides whether the camera stalls, and the 64GB writes more slowly than 128GB and above.
