CF vs SD

[kat]

I have the option or either or both..not to sure what the CF card is and the differences.

What do you use?

All thoughts and suggestions welcomed!!!!!

my camera(s) only take Compact Flash cards which is not used as much as SD which is a smaller physical size, but both come in the same capacities. I think 64gb is the largest, but I use 8gb cards. I don't know the technical or performance differences, but I sort of wish I had the option to use both since SDs are easier to find in a pinch. But with 4 cards on hand, I don't think that pinch will ever come.

Did you upgrade to the D300s?!! :) Compact flash cards were able write and process data at a faster rate then SD cards but I believe that the SD cards are catching up! My D300 uses only the flashcard. I think with the D300s you can record to both simultaneously or put jpegs on the sd while you put nef files on the compactflash although I could be wrong about the last thing. Not all SD cards are created equal some are much slower then others so basically if you are using your cameras maximum speed 6 or 7 frames per second or whatever it is you need a card that can process that info quickly. I am just kind of rambling here but that is the gist of it.

As Jas said it has more to do with the read/write speed then anything else and two way communication.

Yep, the CF cards are a little faster than the SD's. That didn't enter into the equation when I move up to the 300S because I already had roughly 64 gigs of SD storage on hand and SD's are just fine for every day shooting. However, when I set up the four available custom shooting banks I did set the CF card as the primary with the SD as overflow for action photography or any other time that 8fps comes in handy.
