The Canon C70 has a dual SD memory card configuration supporting the fastest SD cards up to the UHS-II V90 speed class.
To use the max bitrate of 645Mbps (80.62MB/s) with the new Cinema Raw Light. You need the fastest v90 UHS-II cards if you want. But you can use a V60 card in the second slot to record Proxies.
To use the standard intra-frame XF-AVC mode records at 410Mbps or 51MB/s, you need V60 UHS-II cards.
The HEVC (H.265) codec with a max bitrate of 225Mbps or 28MB/s only requires UHS-I V30 or U3 memory cards.
