UHS-I tops out below faster cameras' capabilities — cameras with UHS-II card slots benefit from UHS-II cards for deeper burst buffers and faster offloading, which the Extreme PRO can't provide.

128GB fills quickly with 4K footage — at approximately 300MB per minute for 4K/60fps 10-bit, 128GB provides only about 7 hours of recording before the card is full.
Source: Amazon.ca reviewerThe SanDisk Extreme PRO is the default SD card recommendation for any UHS-I camera, and for good reason. 90MB/s write speed, 200MB/s read, proven reliability, and included recovery software at $35 is excellent value. Only upgrade to UHS-II if your camera supports it and you're shooting high-bitrate formats or long burst sequences.
