XQD Card cancelled.

Where did you get your card? I only have one, but now I think I might get a back-up if yours died already. Only one of my SD cards ever gave me a problem and that was the plastic lock that broke on it.

I do not understand some of the comments here. The speed, thru-put really, is a function of the internal circuitry of the mechanism (camera in this instance) first _then_ the speed of the card where some form-factors are faster than others by design. And every card that I've looked at tries to hide that spec behind verbage.

And the camera buffer to hold data until if can be written to the card is really an important part of that equation.

Anyway, I agree that card manufacturers are not great at giving out meaningful specs about their cards. Even where they do, real world specs almost never match the supposed maximum speeds.

Here's a link to some speed testing on many of the commonly available SD cards:
