- The 170MB/s read speed requires a UHS-I compatible device and reader to reach maximum throughput.
- Write speed of 90MB/s may limit performance in cameras with very high bitrate recording modes.
- The bundled card reader is a third-party accessory and may not match SanDisk's build quality.

- Does not include UHS-II support, so it cannot take advantage of faster UHS-II device interfaces.
