I know there was a post on here at some stage but I can't find it. So, what are the differences/advantages/disadvantages between CF and SD cards?

I just got a 1D mk IV and previously just used SD in my last camera. Now that I have the opportunity, I'd love to get the best card possible. I was looking at the extreme pro line that sandisk has, in particular the 95mb/s cards, of which they have SD and CF, both vastly different In price. Is it worthwhile going for the more expensive CF? If so, WHY?

Any advice would be much appreciated!

And yes I plan on shooting sports at 10fps full RAW...

Thanks.
