So why does Canon provide such small buffers? That's not even a gig of data. The memory technology is there as there are 3 gig video cards with far faster memory busses.

The nikon d4 has over 100 shot buffer without even a card in place.

The D4 doesn't have over 100 shot buffer without even a card in place. Look at the Rob Gailbraiths or any other test with it. He got 86 shots from it in a 30 sec burst with a Lexar 1000x card. And only 54 shots with a standard Sandisk card.
The only way to reach 100 is if you shoot smaller compressed jpg files

That 12 FPS is an audible orgy. Nice. I mean, I had it with the A77, but only for 1 second, and the sound of just a shutter working (and no mirror) is just a little less manly.

I'm also amazed at how quiet that 5D3 quiet shutter is - wow.

D4 with a Lexar 1000x CF card will do 66 continuous frames at 10fps. My guess is the 1DX at 10fps would probably be in the low to mid 40s? Two seconds of additional continuous action is considerable though.

The question always comes up: why would anyone need to shoot continuously for that long? At least in my shooting experience, there can be times covering sports when a play develops into one that is much longer than anticipated. For example, in football, focusing on the QB as he drops back and shooting him doing so (perhaps anticipating a sack) as he throws or hands off, then continuing to shoot the play, which becomes a long run or catch and run for TD, then photographing the reaction/jubilation afterwards. This can easily spread out over 5-10 seconds of nearly continuous action, is difficult to predict and therefore difficult to conserve buffer space. Shooting Jpeg helps, and sometimes is the better option.

In the scenario you give her, I don't belive anybody would press the shutter button at the highest speed all the time
And the Nikon also have a little bit less resolution of course

Lars, believe whatever you like, as I know you can be difficult to persuade otherwise. Quarterback drops back and rolls out looking for a receiver, linebacker in pursuit - 10-15 frames easily - pitches it to a nearby running back, breaks a tackle and punches through a seam in the defense - 10-15 frames - makes a 20-30 yard run - 20-30 frames, based on the rough average of 10 yards per second. As you can see, it's possible to hit a relatively generous buffer limit. No, it won't happen all that frequently, but I'd much rather not have to think about it. Of course not all of those images will be keepers, or great, but it's good to have the choice and at least for my client, they expect a broad selection of images to meet their production requirements. Having shot roughly 200 NFL football games for them now, most of which have been on digital, starting with the original 1D, I have hit the buffer wall a lot and the limitation conditioned me to subconsciously conserve buffer capacity whenever possible by letting off the shutter after about 1.5 seconds. But the consequence has been missed shots. It's really only with the 1DIV where the buffer has been O...K..., in part because of UDMA6 support that emptied the buffer in about 7 seconds, rather than 25-35 seconds in all previous 1D cameras.

Thanks Stan!

10fps is interesting... about 50 frames before it stutters. Unfortunately you had the strap over the counter and it wasn't possible to count the frames in the 8fps video, but considering that at 6fps the camera does around 100 frames, splitting the difference between 10 and 6fps, should allow around 75 frames at 8fps... give or take.

I shoot horse racing at or near the finish line and sometimes the buffer is not enough if I start shooting too early. With the additional shots with the 1dx, I reckon it is just about perfect. I do not need anymore. Larger buffer would be good but not necessary.

Do you mean when they're both in silent shutter mode? Because otherwise, they're the same to me.

The 5D3 sounds substantially quieter to me. It's a little quieter in normal shutter mode but much quieter in silent mode.

I really disagree, personally. The 5D3 if anything sounds worse, has a "higher pitched" metallic sound. But I'll agree it's way quieter in silent mode.

The last movie shows both in normal and in silent mode... You can compare directly.

That's the video I am referring to.

The Digital Picture has an mp3 of a 1DX burst where Bryan gets a 4.8 second burst @ 12fps before the buffer fills. Uses the same Lexar 1000X 32GB card. Stan's full speed burst is only 3.5 seconds. Curious to find out what differences in shooting conditions and settings caused this.

Thanks for all the vids....I've been happy with my 6FPS (at the best of times) on the 5D3 and never really missed my 8FPS 7D. However, that 12FPS is simply amazing to see/listen to. Could you post the 14FPS jpeg just for kicks? Would love to hear that

Maybe my card was tired. My ISO was 200, maybe his was 100. Maybe his frame rate was lower because the battery was lower: it's documented that the 1DX will slow down on less than full charge, regardless what you set it to. So even in 12fps setting it very well may be running only 10 or 11.

I don't know.

Does anybody know what the max write speed the 1DX is capable of to the CF card?

If the 5D2 is any indicator, then it's firmware dependent. Since the most recent 5D2 firmware, it got wings... I can imagine so would the 1DX.

What I'm really wondering is if I should get the Lexar 1000x card or if the 90 mb/s Sandisk Extreme Pro's would be just as good.

They are not as good by far, even in the 5D3. I have the 64GB ExtremePro and it's a slug in comparison.

Sound like an old movie projector.

12fps is insane.

It's amazing how much faster 8fps seems than 6fps.

On my 1D IV I had L speed continuous set at 5fps and then changed it to 6 as 5 was glacial. I then changed it to 7fps and even that's a noticeable step up from 6. 5D III with 7fps would have been very nice.

As I read the R. G. data table the D4 does either 108 or 110 shots with the Sony cards. That's a lot more than 37 if the data is comparable. Yes I would like to have 12fps but I also want more than 3 sec of, continuous, shooting so I would stay with the D4 (with which I have never filled up the buffer).

No it does not do that in RGs test. It does 66 shots with Lexar 1000x cards and 76 shots with the XQD card (with 14 bits lossless compressed NEF files). And that's if he turn off the active-D lighing and similar stuff.
The D4 also has smaller files and less resolution than the 1DX. If shooting very long bursts like 70-80 shots the D4 will be faster than the 1DX. But if shooting bursts like 20-30 shots which also is much more common, the 1DX is faster than the D4.
Remember that 3 sec of continuous shooting with the 1DX gives you more shots than 3 seconds with the D4. Even when it has more resolution.
The 108 and 110 shots you talk about in RGs test, that's when he is shooting continuous with the D4 for 30 sec. So the D4 will give you an average of about 3,5 shots every second then
