I dont believe you! you and your magic symbols! we should just burn you at the stake! or get some virgins to dance in the moonlight naked!
I will have to do some tests myself when I get hold of one.
What is the write speed (to SD* cards)?

Do you think you'll get a D7000, then, Hearty?

(Still not fully recovered from my long stretch of unemployment :-( ). I was hoping for the D5000 replacement to come out this week as I may go for that instead and wait for the D300S Replacement as well. I kinda like that level of camera.
... maybe I should just sell my S5Pro .. sigh its such a nice camera. Nah.. I will probably get the D7000 in a few weeks time. the prices have come down a lot now here in OZ land.

Has anyone tried the sandisk extreme pro? i'm thinking of getting the extreme pro or extreme memory card for the d7000. if there's not much difference at all especially in video recording in terms of speed then i'm better off w/ the extreme :)

I have no personal experience with either, teeboy, but I have used slower cards and have experienced no problem with recording video the highest quality settings. One thing you can get from this thread is that even with the $20 16GB Transcend cards I bought myself for Christmas I get 9MB/s transfer speeds. The D7000's video will not be any higher than 3MB/s (24Mbps), so unless you need the card speed for stills or you need faster transfer to your computer it won't make any difference.
Welcome to the forum.

Depending what your definition of "significantly" is and what you are using now, it would clear it faster.

right now im using a platinum ii 100x 8gb card(it says 15mbs/s). so it would clear it faster? i read somewhere that cameras can only clear images at a certain speed no matter how fast the card. so would the extreme pro be wasted on the d3100?

As TaoTeJared commented at the beginning of this thread, it is enough to have a Class#6 card, faster cards will not speedup the camera processing/saving.. but it may speedup the download-to-your-computer speed. (e.g. using a faster card-reader for reading the SD card.)
About the class number and speed rating of SD (Secure Digital) cards can read here: http://en.wikipedia.org/wiki/Secure_Digital
Beware of the huge confusion between Mega bits per second or Mega Bytes per second, this changes the numbers by a factor of 8 (8bits=1Byte)
Hope it helps.

I think the Sandisk class 6 cards are 24MB/sec, so it's more like 4MB/sec x the class number.

Oy...too much thinking going on 'round here.
http://en.wikipedia.org/wiki/Secure_Digital#Speed_Class_Rating
Class # x 1 MegaBYTE/sec (8 megaBITS/sec) = minimum sustained speed

Just to add more fun to this thread, I found at work, when using SD cards for recording images from a PillCam, that the write speed of a card is not the only parameter you need to look, also, the write speed may change as soon the card gets full, also it changes according to the age of the card (heavy used cards may take more time to write than brand new ones due to fragmentation or free clusters management.. (Every manufacturer does its NAND/NOR flash memory management differently, and not always published).

I think it does not matter whether the tester chose 15,25 or 50 images in his test procedure. The important part is that there was no difference in result whether using 30 MB/s, 45 MB/s or 95 MB/s rated cards. The limitation was the D7k's write speed.
Nikon have been rather pissy about inquiries about the write speed of the D7k since the very beginning. Their bad attitude about customers has done little to build brand loyalty or trust. They behaved like a bunch of knuckle heads and deserve to be treated as such.
The point of the linked article was that you get more 'bang for your buck' with a 30 or 45 MB/s rated card than with a 95 MB/s card. As the price drops the price premium for the 95 MB/s card will also so that you may be faced with a choice of buying cards that outperform your current camera so that they will be prepared for the next generation camera that has a better write speed.
The question no one seems to have any idea about at all is whether the write speed of the D7k is controlled by firmware (and hence capable of being uprated) or is hardware limited. My guess is that it is hardware limited, but I have no basis in fact for that other than my suspicion because of the poor way Nikon have treated customers about the entire affair.
Let's face it, 6 fps sound nice on paper, but is of limited utility when you can only do so (in RAW) for 10 exposures. After that the exposure rate drops to less than 2 fps until the buffer clears.
The 95 MB/s cards do not seem to be well distributed through the retail channels at this point. In a few months perhaps they will be and the prices will be more in line with the 45 MB/s cards.

In the past few weeks I was working in porting a SD-Card driver for an embedded Linux device at work, and there are many factors you can blame when write speed is not what you want...
As mentioned before, the D7K does not need hyper speed cards :), the more faster cards will help you only in downloading the photos from your SD card.
There is another factor to take into account with SD cards, that is related to the SD card embedded controller, that may stop the write procedure in order to run some housekeeping procedures in balancing the usage of the card.. and this may hit you. The housekeeping may take almost a second, which may cause the write rate to drop below the requirements of the camera.

I actually asked Nikon support essentially this same question but from a slightly different angle. I was considering getting an Eye-Fi card for the second slot and only saving basic JPEG to the card (so I can preview on my iPad), using the primary to save RAW. I was concerned about the speed differences effecting performance.
The response I got from Nikon was that the two slots operated completely independently of each other and writing lower res images to a slow card would not effect the performance of the other card. They recommended using the fastest Class 10 card available and implied that the camera can write faster than any card available today. I asked explicitly about the SanDisk Extreme SDHC Class 10 (30MB/s) 32GB card, and the reply indicated that it would support the card at full speed.
