You can get a very good idea from this

Unfortunately the 300D does not benefit hugely from a faster card, indicating
the write speed is limited by the camera rather than the card.

Do compact flash memory cards with a faster write speed (40x) allow you to
take more photos per second on an EOS300d? Or am I just as well buying a
normal speed memory card??

No, the frames per second won't be affected by a faster card. That's
limited by the hardware (image processor) in the camera. A faster card will
(theoretically) allow the camera to write the buffer faster to the card, and
allow faster downloads through a USB2 card reader. The 300D is USB 1.1, so
faster cards won't make downloading through the camera any faster.

you'd probably notice a difference in a USB 2 or built in card reader

The card has a capacity to trnsfer data but the camera can only go so fast
in transferring image data

It depends. The 300D can take four pictures quickly and store them
internally. As each picture is taken, it then starts the process of writing
the image out to the compact flash card. Once a picture is written, the
internal memory buffer frees up and can take the next picture. The faster
cards will make the difference in the 300D taking 3 seconds to write an
image vs. 6 seconds.
