Default Does compact flash record faster than SD?

does the type of recording media you use effect how long it takes the camera to record it? Is one type of media faster shot to shot than another?

If the camera you use says it will shoot high frame rate movie, then it will be as fast as the media type and size it specifies. Smartmedia is very fast for cams that use it, but SM has a 128Mb size limit. Microdrive is very fast, but takes a bit more power, Compact flash is becoming fast, but actual speed performance might be very dependent on the camera. SD has the potential spec. for large sizes, but they're still below the 1Gb affordable barrier as far as I know. Cams out now will specify the max size of media. Be careful, just because the media spec might get bigger in future, doesn't mean your cam will be able to use it - read the cam spec carefully!

The direct answer to your post, is in most cases it is the camera which is the bottleneck, so high frame rate movie option is a good sign. If your camera has big fast buffer memory, media speed is less of an issue - unless you turn it off during writes! CompactFlash brands/formats/speed rating can, achieve optimum in some cams, however consistency based on media speed rating alone is not always a guarantee.

The size of file you shoot, will stretch the cams internal buffer/processor/media write speed. Shoot uncompressed files 18Mb plus regularly and you'll need fast cam and media!
