flash card speed. Ok I have been shooting highschool

[insurancepi]

football at night for the past several weeks with a 70-200 2.8 lens and it has been going pretty well. Here is my question, with the 300D I can shoot only 4 frames per second and then the memory in the camera writes the pictures to the flash card(which takes a little time), then I can shoot again, will the speed of the make a difference during this writing process or does the speed of the card only make a difference when uploading to your computer?, or both.

Are you sure your shooting 4 frames per second with a 300d? Or did you mean a burst of 4 before the camera reads to the card?

Personally I don't see much difference in write speeds of cf cards. I bought a 40x Lexar 256 when they first came out and if there is a difference between that and the old San Disk I had I couldn't really see that in real time.

shots then it writes to card.

Card speed doesn't really make that much of a difference in the Rebel. It will make a difference for an external card reader, but there's not much you can do about the slow buffer writes besides buying a new camera :(

Take a look at:

That's Rob Galbraith's CF speed database that shows which cards provide which write speeds in various cameras.

You will notice that for most fast cards the 300D is the bottleneck and you will not get significantly better results from an 80x or 60x card (as opposed to, say, a 40x card). They are only faster when downloading via a USB2.0 card reader (and more expensive).
