Memory card speed question

[michael23]

Hi can someone tell me what the difference is between the 30 or 60 mbps compact flash cards from sandisk and other manufactures which state 133x, 266x, 400x, 600x. Which is faster? As I can only get 325 ish raw pics on 8gb on my 50d, I need something bigger for my holiday in october.
