the FFT-CCD is distinguished by a larger pixel area, with bigger photodiodes and transfer channels. This means more electrons can be captured. A high signal/noise ratio can therefore be achieved together with a wider dynamic range. Final images benefit from more exposure latitude, greater detail and less noise.

this gets mentioned in equivalence debates, the amount of light falling onto the sensor, and a bigger sensor with bigger pixels captures more photons.

Not necessarily. A 4/3 camera with a lens two stops faster would capture the same number of photons as a FF camera with the slower lens.

But that of course does raise an interesting question ......
