CFI versus CFII

[quint young]

Besides the size difference, what, if any, is the difference between type I and type II compact flash media? Can type I be used in a type II device - I guess I am asking if they are backwards compatible?

I just today found out about the size difference. I was at Best Buy yesterday looking at the CF media and I couldn't find anywhere on the packages a designation for type I or type II. I may not have looked closely enough, but it probably should have been more clearly labeled.

From the Compact Flash Association Website -

The only difference between CF Type I and CF Type II cards is the card thickness. CF Type I is 3.3 mm thick and CF Type II cards are 5mm thick. A CF Type I card will operate in a CF Type I or CF Type II slot. A CF Type II card will only fit in a CF Type II slot. The electrical interfaces are identical. CompactFlash is available in both CF Type I and CF Type II cards, though predominantly in CF Type I cards. The Microdrive is a CF Type II card. Most CF I/O cards are CF Type I, but there are some CF Type II I/O cards.

Hope that helps

CF type I cards are backwards compatible to the CF type II cards. Most of the cards out there 256MB and under are type I cards. Be careful of the larger capacities though, because often times it is cheaper and easier to build a high capacity type II card than a type I card. The thicker type II design allows for chip stacking (cheaper and easier design).

P.S. All Viking CF cards are type I cards and will work with all CF card slots. If you are really concerned about getting the right card for a particular camera check out this latest DPReview affiliate site:
