My oldest card I have now is almost 3 years old now... I better keep an eye on it than. Thanks for the input but I'm just wondering, what brand of card that photographer you've talk about failed anyway?
Well, wish me luck guys!
BTW.... Oh! I picked up an 8G Sandisk Extreme IV 
Take care,

The ones that failed were cheapies- that we (the rest of the photographers in the studio) have told him he should get rid of- they were standard CF cards and he was shooting 3-4 times a week with them.
one more thing about flash cards: do not buy cards from china on Ebay- I got one a few years ago and it wouldn't work in any camera- 
Hey!
I see... well, he cheap out and didn't listen to you guys

Yes, I've heard horror stories about CF card off eBay. That's why I don't buy CF card off eBay.
BTW... I used my new Sandisk Extreme IV 8GB on Friday and Saturday at a photo gig and it perform flawlessly in my DSLR with great speed in a hot 94*F heat! And with 8GB I had to change card once this time.
But I have to admit that there is a fear of having a lot of files on one card. If it fail that would be nearly the whole work for me
Well, I guess is paid to buy a good card from a well established brand.
Take care,
Buddy
