Originally posted by jersey I never remove SD card from a camera and use only cable transfer. I do not even have SD card reader. I suppose there are cons and pros for both approaches.
I could imagine SSD in K-3 Mk III instead of dual SSD, as for action camera with need of high FPS solid state drive would be great. But I doubt there will be much use outside of such fast action cameras. Plus while reliable, they are still relative easy to damage with heat or cold or even some breaks in write/read sequence. SD card simply dies, you get new one. With SSD this may be an issue. And I doubt there will be enough space for PCI slot in a camera to make removable SSD.
I always use a card reader and never connect to the camera directly. My card reader is much faster than the camera, and I don't even have the fastest card reader. This might be more important if you take more photos, to reduce the transfer time significantly. I'd rather plug & unplug the card than the cord to my camera, as if the card wears out, it's easier to replace than if the port on my camera wears out.
If you want faster removable camera storage, the CFExpress someone mentioned above is the fastest removable card out there today.
