Is it possible to grab video or still frames directly into a NAND flash? Is it a common practise or are such devices still too slow?

Consider that many digital cameras use flash "discs" and handle
640x480 @ 30fps (2MiB/s mjpg canon s2is). So it is possible.

I'm not sure digital cameras store data directly into flash discs. They might use some SDRAM as buffers. And if they do image processing they can't avoid sdram, unless the processing is done by hardware. So this is my concern. Anyway i would store the raw image data directly into flash and no image processing would pose any overhead. Maybe a small FIFO could reduce the "timing gap" if any...
