where there’s smoke there’s forum fire
I use 4gig and 8gig cards. Forces me to remove and put in a new card in case one fails.
Sandisk all the way for me. Lexar Pros are good - they just don't sell them around here.
Nikon Cameras seem not to like Kingston very much so I would stay away from those.
Just so everyone can make it clear to me.. If I use the video feature, it will only be for personal stuff of my child, nothing needing to be high quality. And I won't be shooting super fast in succession.
Would a class 4 SDHC card be okay? Or do I absolutely need a class 6 minimum?
You should be fine, Kithic. The video won't be higher than 2.5 MB/s and a class 4 card should handle 4 MB/s at a minimum.
Something that I'm wondering that I haven't seen addressed: is there any drawback (buffer bottlenecking, etc) to using cards of two different classes? For example, if I use a class 10 8GB in one slot to shoot lossless 14 bit and another 8GB in slot 2 for high-quality JPEG, will this cause issues? The reason I ask is, while I'm not looking to get dirt-cheap cards, I may not necessarily be looking to spend top dollar initially (getting the camera itself is going to wipe out a decent chunk of my camera budget, and there are other things, like a tripod/monopod and a speedlight) that I'll be looking to pick up at the same time, so I'm looking at memory as an area in which to economize temporarily.
Thoughts?
Makes sense that it would create a bottleneck- you'd be able to write a different speeds now. I'm sure it'd create an even bigger bottleneck if you were writing RAW to the slower card and the jpg to the faster card.
Only one way to find out!
@NSX: Well, that was part of why I thought I MIGHT be able to get away with it; as long as I'm using the faster card for the more memory-intensive format, it might work, right? I'm assuming the camera prioritizes according to the formats used (but I'm well aware what happens when you assume :) ).
Interesting discussion on sdcards here.. I am not sure but I think the class of the sdcard is the MINIMUM bps. Therefore a Class 2 card may perform better than a Class 4 or even a class 6 if its from a good manufacturer. similarly a class 6 may perform better than a class 10 from a dodgy maker. Some card companies order(from their manufacturer) the same card at a certain level, say class 10, but order a zillion of them(cheaper by the zillion :-) ) then label some of them as class 6 and class 4 and sell them as 3 separate products! (That's marketing for ya!) So if you are lucky you may get a class 10 card when you buy a class 4 or 6!
@aslightdelay - I think the main bottleneck lies in recording both formats. There would probably be a slight speed difference but probably not enough to notice as long they are both class 6 or above.
I have seen a large bump going from class 4 to class 6. I gave all my class 4s away and upgraded. Rule of thumb I use is to take the "Data transfer rate" cut in half and that is the actual usable MB speed. Write speeds are usually 1/2 of read speeds. Some companies post read transfer rate instead the write speed.
@heartyfisher - I have read and experienced this with brands OTHER than Sandisk and Lexar pro series. For the majority of users, they will not see much of a difference. I did have a boss buy a bunch of crap party SD class 10 card to save $400 for mobile computer technology and the difference was enormous at that high level of data transfer rates! We swapped them out. I took them for my G11, and I could not tell a single difference until I was using a card reader to download them to my computer - then it showed how crappy they were.
Like everyone else said. Class 10 Sandisk works great on my d7000. I haven't had one problem with it yet and you can get a good amount of shots on continuous mode.
I use sandisk extreme cards exclusively because they have never failed me or any of the photog's I know personally. I have 1 Sandisk ultra 16 gb card and I hate that my D200 chokes up after about 10 frames when using it on continuous shooting. As to video you cant go wrong with the class 10 cards...
This is how they're made if you're interested...

Maybe. Who knows? Find out and let us know.

What class was it? Perhaps it was the D200's buffer?
I use a class 4 card with the D40, not a big issue as file sizes aren't massive and the D40 isn't a speed demon.
Nice thread...
Question: What is the max write speed the D7000 has?
Therefore you may not need faster than the write speed of the camera..
Few years ago, when I was in the search for a CF card for my D70s, the market was already populated with faster cards than the camera write speed. People on different forums were advising to get the latest expensive ones (above 80x) when the camera was capable to write at a speed around 40x for the D70s and around 33x for the D70, (The rate multiplier comes from the old audio CD data transfer rate which is 150 KB/s.)
I use two Patriot SDHC 16gb Class 10 (part# PSF16GSDHC10)
I have some 2,000 pictures taken and half a dozen videos, and have had no issues.
Go for Class 6 at least, not lower.
Cheers,
Someone shared a nice link about D7000 write speeds with various cards here: http://nikonrumors.com/forum/topic.php?id=2712&page=2#post-54910
Another vote here for Transcend. I've never had a problem with them, and their class 10 cards have always kept up to speed, even with the demands of the D7000 . Here you can pick up an 8GB card for £7.50 so I'll be stocking up with more of these in the near future.

The D200 is supposed to get 22 raw files on a burst, but with the ultra cards it gets about 10. My D90 is only supposed to get 11 raws on a burst but with the extreme it surprisingly does about 26 and the write time is faster as I can shoot about 2.5 fps when the buffer is full as opposed to a frame every few seconds on the d200 when the buffer is full. I know the D200 and the D90 are 12 bit raw shooters but the D90 also has a larger file size than the D200 as it has 2.5 million pixels more. My D90 does go down in performance when I use any other cards too although I dont see a difference between the class 6 and class 10 cards (The cf I use in the D200 doesn't even list a class).
Cool vid BTW Broxi, It makes me think highly of my local hospital...

I had bad experience with Transcend CF cards, while Sandisk or Kingston were O.K. for the D70s although Kingston and Nikon have a non-friendly reputation (As I have read before in this thread)
Funny, just ordered two Sandisk Extreme Pro 8GB for the new D7000. They should all be here by Friday. I suspect that the Extreme is fast enough to handle the full write speed of the D7000, but I'm haven't been able to confirm that one way or another. I know the extra speed will be appreciated when I load them on my laptop as the slot is built into the UDMA controller so will probably read at the full speed of the card.
I use the CF Sandisk Extreme Pro in my D700 and it has been great. I have an express card bus reader for my laptop for that one and it flies when downloading.
I have both the sandisk extreme class 10 and the sandisk extreme pro UHS. It feels like the new UHS is a bit faster, but i have no hard figures to back that up.
When I first bought my D7000, I bought a few SanDisk Extreme IIIs, rated at 30Mb/sec. I lost one, and needed more, but all I could find on the B+H site last week was SanDisk Extreme (no Roman numerals) at only 20Mb/sec. The Extreme IIIs, apparently, are no longer in current production. Anyone have a clue what exactly replaced the "IIIs" and why the datarate dropped 10Mb/sec. on the current "Extreme" product?
[The Extreme IIIs worked fine for both stills and 1080p24 video, by the way.]
@studio460 - FYI - I just searched and they are for sale at B+H and everywhere else.
