When taking photos using the camera's shutter release the camera can take photos at its normal frame rate (e.g. 5 frames/sec for the 30D and 3 frames/sec for the 400D/Rebel XTi and 450D/Rebel XSi) until its buffers become full. After an initial camera processing delay the images will be transferred to the PC at approximately 3 to 5 Mb/sec. The camera is able to continue taking photos at a reduced frame rate until its secondary buffers become full and then has to wait for images to be downloaded before taking more photos.
