My EOS-1D Mark II N will support CF cards up to 16GB and SDHC cards up to 8GB. Yet, it does not support the UDMA (high speed) rated cards. Thus my maximums are a non UDMA CF card, and a standard speed SDHC card. I cannot find any reference to a) what is 'standard speed' for an SDHC card or b) if there is a limit to the read/write speed of the camera.

The maximum read write speeds are not published specifications. We apologize for any inconvenience that this may cause you.

The super large CF and SD cards are not desirable. Before I retired I shot professionally and can tell yoiu, especially on a
1D Mk II n, you don't want or need them. Actually 4 GB cards are great. The reason is, cards fail and when you have a large card you lose large!
It is far better to have several smaller cards and change them as needed.
The 1D Mk II n is a fantastic all professional camera. It is one of the best Canon has made. It is possibile to write RAW to the CF card and jpegs to the SD card.
As to write speeds, the 1 D Mk II n, will be ready for the next shot way before you are.
Great camera! You can earn a living with that camera.
