Which is a better format, SD or CF?
CF is better in terms of capacity (max 64GB) and transfer speed (133MBytes/sec). Max capacity for SD is 4GB (variant SDHC is 32GB) and transfer speed is 20MBytes/sec. But SD is better when it comes to size because it's smaller and thinner (2.1mm vs. 3.3mm for CF).

If you go for capacity, ruggedness choose CF's.
SD's usually used as storage medium for Electronic devices like mp3 player, mobile phones,game consoles, GPS, and PDA's because of its small dimension.
