The real write speeds at this time for SDXC 1000x cards is 155 MB/s. The version 2 XQD cards that cost $140 for a 64GB card have write speeds up up to 210 MB/s (dependent on how fast the camera's processors can actually deliver the data to the card). The ver 2 XQD that have a 440 MB/s theoretical write speed cost $204 for a 64GB card.
To actually need a 200 file RAW buffer at 10 fps with the D500 one would have to shoot continuously for 20 full seconds. I would be interested in who has ever had a reason or occasion to shoot continuously at 10 fps for even 10 seconds and what they were photographing.
Where I have needed to use maximum fps settings with my cameras the actual action I was attempting to capture was over in less than 5 seconds. There is also the aspect of shooting at 10 fps and whether there is going to be any usable difference between frames 88, 89, 90, 91, etc that requires shooting 200 frames to be safe.
For my part whether shooting motor sports or wildlife I have not needed 10 fps and used a slower setting to get fewer nearly identical images that I would have to sort through and delete later. This also speaks to the workflow problems with the amount of time it takes to import 2000 RAW image files at the end of the day into Lightroom or to get them processed in Bridge to be able to start to review and delete duplicates. The bottleneck has simply been moved to the computer from the card reader and there is no net time savings, quite the opposite.
Take a look at your own pictures taken over the past years and see how often you missed something because you could only capture 30 frames before filling the buffer. The Canon 1d X by the way has a 37 RAW file buffer but I have yet to read of someone commenting about shots they missed as a result.
There is a point where the product marketing people are using a capability to hype their product as being better than a competitors even though it has no difference in real world use. It is like Ford and Chevy each coming out with engines with more and more horsepower that can spin the tires more for customers that find that appealing.
This is not really any different for the hype around 1000x versus 600x cards that provide little or no benefit to the majority of users but do greatly improve the sales and profits of the memory card manufacturers. They are already up against it as there is a limit to how many image files can be captured in a day or even in a week and so photographers spend less and less each year on memory cards with their falling prices. My first memory card was an IBM 1GB microdisk that cost me $700. Now I can by a 64GB SDXC card for $35 and that does not do much for the sales of the card companies. But if you can convince people to spend $203 on a 2933x XQD card instead of $35 on a 1000x SDXC card then the company has helped offset the decline in card prices. ...Show more →
