"It doesn't seem to work like that..."

Nikon seems to factor in writing to a "normal" card in calculating the buffer. There also seems to be a variable lag in writing (which shows up once the buffer is full) - check out some the Performance tests at Image Resources: http://www.imaging-resource.com/PRODS/nikon-d800/nikon-d800A6.HTM .

I would add that most RAW shooters will shoot either 12 or 14 bit lossless. The only silver lining here is that with the enhanced speed from a 95MB/s card the buffer emptying time could be quite short. For instance, a D300s with a fast card can shoot three cycles of 17 frames at full speed in 30 seconds. It could be that in 1.3x crop mode and 12 bit lossless a D7100 could shoot five cycles of 12 shots at a full 7 fps. And in DX mode it might be able to approach 6 cycles of 7 shots at 6 fps in 30seconds.
