@adamz: I can't agree with you. Obviously if you accidentally drop your 64GB card into water on the last day of your vacation you've lost everything, as a pose to losing one of you 16GB cards. But not too long from now, a 64GB card is still going to be useful while you use your 4GB as a settings backup for your camera.

alpha - for sure You don't have to agree with me, but try to put 64GB of data on DVD, or even on BR - in first case You gonna need 16 discs in second case at least 3 (not to mention the price) - I know that Your backup plan is totally different, but mine was pretty much like Yours till the time my aperture library was bigger than 100GB (right now around 200GB) and it started to slow my work, not to mention the time need to backup the whole thing; then I switched to backing up the cards, as I copy them to dvd - one 4gb card = one dvd, it saves me time as it saves time to a huge number of photographers worldwide. One more thing, I guess You never used databank, try to copy 16gb card to it and You will understand my point of view.
As for 64GB cards I'm really please that sandisk announced them, but IMHO it's just to much for daily use (at least for now, and for all the sub 20mpx cameras), unless You really shot a lot (and really need this amount of data), or You are storing all Your photos (since the first shot) on one card - which I've seen on some of my friends cameras.
Guys, I would stay away from Kingston. When I went to Japan I had a 256mb Kingston SD card in my Nikon point and shoot and it just happened to malfunction- I nearly lost all my photos. I moved to Sandisk and I haven't gone back.
If the regular SD cards are too slow for you guys, go for the Extreme II instead of the Extreme III. They're slightly older, but because a D40 can only be so quick, the card is already faster than the camera's buffer anyway.
My 8 gig and 2 gig cards are going very strong. I love the 2 gig in my point and shoot now- I never need to worry about overfilling my card, whether I am shooting video or pictures. I go through 2 full batteries without even touching the limit of the card.
I use to think it wasn't a good idea to carry more than 256mb of files on a zip disk too. You know in case I accidentally dropped it in water and lost all my photos :^)
I've had all types and all brands of memory cards fail on me. I guess I just put my equipment through some heavy use.
udma 6 is the same as ata-7. It tops out at 133MB/s. Check out the matrix.
Some good sites for CF speed comparisons:
Backing up to DVD may not provide archival storage. http://www.larryjordan.biz/articles/lj_dvd_life.html
The lifespan of "burned" media (CD/DVD) is variable dependent upon many factors. Raid drives and redundancy are the best answers.
My God and I thought my Sandisk Extreme IV 45mb/s was fast. I want this (90mb/s). Whats the limit on how fast can my D700 can write I wonder.
