I am just the opposite. I had 4 Gig cards and lost one with all my images on it. Now I use 8 gig cards, one of which usually holds my days shooting. I figure the safest place for the card is in my camera. Having many laying around is courting disaster IMHO.
I personally don't like Kingston. I haven't had the best of luck with that brand (granted it has been a couple years at least so...) In my D200 I have an 8gb PNY. However the Kingston don't look like a bad card and seems to have a pretty good write speed. I will have to watch this thread and see if you like it. Because if you do, I will get one. Lol.
I have only had one failure with a card and it was a PNY 2Gb card. I will never shoot PNY now. Every card I have now is SanDisk and I have never had problems with them.
On another note... does anyone on here have any experience with BuyDig.Com? They have the SanDisk E-III 16 Gb cards retailing for 160.00 with the SanDisk rebates. ($90 back for 1 card, $190 back for 2, and $300 back for 3 cards.) That puts puts it at $70.00 for a 16Gb card if you just buy one. I am looking at getting a couple of the cards and that moves the price down to $65 each.
Sounds like a good deal of BuyDig is a good company to work with.
I used two 16 gig Sandisk Extreme III's in two D300's for a four day shoot. Blew threw 5950 files total without a hitch. I would say 2/3 of those were from those two cameras/two cards with the other 1/3 being a D3 with SE III 8 gig cards.
No problems. No worries. Smooth and fast.
