The SD card consortium are either a bunch of incompetent fools or a bunch of money grabbing extortionists (or both). The original CF specs (1995) allowed for cards up to 128GiB. More than ten years later the SDHC specs (2006) modestly increases the original SD spec of 4GiB to 32GiB. The latest CF specs (2010) allows for cards up to 128PiB which is several orders of magnitude greater than that offered by this SDXC rubbish.
