Here's a video I took of a Nikon rep demonstrated the buffer capacity with a 260 MB/s SD card. The result was 74 frames. Using the same settings on a 400 MB/s XQD produced 200 frames. This was for 14-bit compressed NEFs.

Exactly what I needed to see, thank you!
Just note that the actual sustained write speed on that SD card is more like 170 MB/s according to reviews. Still, 74 frames is impressive, and I imagine 7.5 seconds would be plenty for many users for a single burst.
Yep, though I'll personally be looking forward to leveraging the 200 image buffer, on a regular basis, I shoot a lot of wildlife action and one of the only things I miss on the 7D2 was the seemingly endless buffer with UDMA7 CF cards. It can be tough to decide between RAW and buffer depth on other bodies because it means I am possibly going to miss something. My original plan was to "settle" for a used D4 when the D5 releases but I really wanted DX for reach. Now we get to have our cake and eat it too, this is very exciting! I am new to XQD but if that's what it takes, so be it. Just need to wait for an XQD sale which I am sure will happen more often as the D500 helps bring that format from pro-exclusive to mainstream.
I may have missed it, does buffer performance decrease if you are also backing up to the SD slot? And has Nikon announced how many estimated # of compressed RAWs fit on a given card? Just trying to finalize my memory budget

Definitely! I've never used more than a few seconds burst at most when following BIF.
I didn't see the need until I started photographing bird fights and diving ducks catching/eating fish. Some of those fights such as bald eagles, cormorants, etc. can really last a while and I easily eclipsed 10 seconds of activity on a regular basis shooting with my 7D2. Though I love my D810, hitting the 33 image buffer during the same type of situation is always a downer So it will be nice to have a purpose built body for the job again!
But totally agreed, standard BIF rarely requires that much of a burst unless by the grace of pure luck the bird is giving you multiple passes to up your keeper rate

How did you get a 10 second burst out of a 7D2? JPEG? When I was playing with one I recall the raw buffer being pretty tiny.
architect7 wrote:
I had to check again, looks like I remembered incorrectly. With my Lexar 1066x CF card I was getting a burst of just under 100 images with RAW only.
Are you sure? Not a single reviewer could get more than 26-30 RAW's out of a single burst at max FPS, with either SD or CF. I couldn't either when I used one. That's awesome if you somehow were though.

The cost of fast XQD cards seems pretty high. The cost of UHS-2 is a lot less, but still not cheap for the 280 MB/s cards. The speed of the SD cards would work for me, though I would still have to replaced my older cards, so something to consider with the camera body.

I hit my 33 RAW buffer on my D810 quite often but I distinctly remember taking considerably more photos in a burst with my 7D2. I remember one specific set of an immature bald eagle in spring so I'll go back and look at the time stamps just to be sure Totally possible that FPS was reduced after ~30 images and I didn't notice but I don't think the drop was ever that pronounced.

Funny enough, right after my original post about waiting for XQD cards to go on sale, Adorama literally put all high end flash memory on sale including all XQD, UHS-II SDXC and CF cards. But you're right, the XQD even on sale still aren't cheap, $230 for 64GB is going to be a hard pill swallow after paying close to $1/GB for UDMA 7 CF cards during the right sales last year. I'm still going to wait since we're still two months away but nice to see some initial sale pricing before the camera has even been released

7D2 can still maintain about 5.7 FPS with a fast card, after buffer is full. Not that bad

I remember not too many years ago paying $450 for a 512Mb, yes Mb, CF card for my Canon D30 (not 30D)!!
You guys were brave. I went digital in 2006 with my first Canon, 6 MP's. Made good pictures from it.
I saw the digital age was there, so I could sell all my old gears for good prices.

That's probably what I remember experiencing, much better than the D810 that drops to 1fps after ~30 images but apples to oranges in that case. 200 images at full fps is going to be amazing.
Less biased images to judge performance? what do you think will be different? all results are based on images taken by an individual using the camera body and whatever lens was chosen to do the job. then processed through whatever software supports it at the time. the results are what the camera can do in the "right" hands. you know pretty much what we all do.
So it will be nice to have a purpose built body for the job again!
