The type of card you require (that is its 'from factor ' if you like) is governed by your camera. In-camera storage has progressed from floppy disks, through micro hard drives (and what jewels of engineering they were!) to solid state CompactFlash and finally to three types of SD Card. Confused? You might well be - so below is the basic rundown of the card family. Remember the first port of call when deciding is your camera manual!
The humble SD card, or Secure Digital card to use its full name, has been around a long time. It dates all the way back to 1999, in fact.

CompactFlash retains a following with cameras because of its inherently greater speed.
