SD Card Woes

I recently had an SD card sort of evaporate....
The card was a transcend card which was used in a Canon Rebel shooting time lapse, so no direct connection to the AF 100. THis particular card was a class 10 card and while off loading the 13 gb of still photos with SHOT PUT PRO, suddenly alarm bells started blaring accompanied by an error message alerting me to the fact that the offload failed.

The card apparently is toast at this point, having failed mid stream in an offload. The card won't even mount when I try that.

At this point it doesn't matter any more, what is lost is lost, however it did get me thinking about how safe SD cards are in general. I am currently using Panasonic gold cards and Sandisk extreme video cards and have experienced zero problems with those two types of memory.

Has any one else just had a card evaporate, never to be mounted again?

So far I am batting 1000 after almost 2 years shooting on Sandisks, Panasonics and even a couple of lowly PNYs.

I think a very useful feature on any future iterations of the AF100 (or any other camera writing to SD cards) would be a function to dual write the same material to both cards.
 
Not all cards are created equal. I'm well over three years with no failures on my SanDisks and Panasonics, but I've had a transcend literally fall apart, the case split open.

I always advise to use the very best possible cards, and if you're gonna cheap out anywhere, cheaping out on your recording medium (or your lens filters) is about the last place to go trying to save a couple dollars.
 
There is no such thing as a card that is 100% fail proof, however the Panasonic Gold and SanDisk are about as close as you are going to get.

What happened to those new Panasonic Pro SD cards we heard about a few months back.

I think they're fully available now, but I don't know anyone who's using them:

It also looks like Panasonic is blowing out the "older" gold UHS-I cards (versus the new black ones), but there doesn't seem to be a big difference other than the anti-counterfeiting code and packaging from what I can tell.
 
I never go cheap on recording media. The card in question was purchased by some one else for a project I have since taken over. What was freaky however was the way the card just upped and died in the midst of a transfer. Bang - dead.

That happened to me with a Kingston 16GB class 10 card. Fortunately, nothing critical was lost.
