Probably more than you will ever want to know about SD Cards. :-) SD Card, like the other types of flash cards are targeted to reach 1 gigabyte capacity within a year or so. Now each SD card actually have 2 partition on it: a "protected" and a "normal" partition. The protected partition is only accessible to manufactures who has the cryptographic keys and is intended for controlling access to protected content. There are if you like 2 bootable VFAT file system on the card. As for the write protect tab, that has to be implemented by the SD Card reader itself as the plastic slider is not connected electrically to the internal of the cards. Are SD Cards inherently better than any of the others form factors? I don't think so. Their main advantage from what I can remember over CompactFlash or others formats, is that they support DRM protected content for things like music or video and they are physically smaller than most.
