So for 64gb, speed is same. Are there anything inside CF card making it expensive? or just use more SD card make it cheaper?

the upper limit for CF cards can be 128PB (128x10^6 GB) and transfer 167MB/s
the upper limit for SD cards can be 2TB (2x10^3 GB) and transfer 104MB/s

CF is pretty big and fast and will be bigger and faster in the future ...
