Default CF card speeds x24 vs x8/x12

I recentlly ordered the Nikon Coolpix 5700. I read a few articles stating that the x24 speed CF card was the way to go. Then I read there is no noticeable difference unless using RAW format. Can any one shed some light on this topic. Thanks!

the tranfer speed will vary from each camera type. nikon will be different from minolta and so on. this link will give you an idea of whats going on.

it deals with pro camera/cf card interaction but will be enlightening. a good link to keep too

the basic reason why raw is faster is because there is no in camera processing done to either convert to jpg/tiff or compress the image.

The reason you're not seeing any difference in jpeg, is when shooting in this mode the output files are so small, that the camera internal memory can buffer the shots (even @ high speed) and parses them out to a slower flash. When shooting in raw or tiff however, the output files are now much larger (x3 to 5 times), and a single shot can fill the entire buffer hence the camera now requires time to empty it's buffer to the slower writing flash! This the reason behind why people complain about camera slowness in the raw/tiff mode.

In fact anyone can see the difference in flash speed right away in their camera when one goes to the video/movie mode and fill the camera buffer up (always limited in most cameras except for the S602) where the camera is locked up until the camera's buffer is emptied. There's less wait time between movie clips as flash speed rating increases. If you never use raw, tiff, or movie mode however, then you'll never be able to tell any difference in CF speed !!!
