Just found your site today (through something else), nice stuff.
FWIW, it is fairly frustrating that you use uncompressed raws for some cameras (and do not state raw size for those who are too lazy to calculate it), and use compressed raws for others.
Do you know why your throughput rate on the D750 is so low? I would expect in a 30 second test you would hit ~1.9 frames/second transferred (57) plus the base buffer of ~15 leading to a total in the 72ish range. In comparison the D600 hitting 50 seems crazy given the much slower peak transfer rate and use of uncompressed raws.
Actually the D600 was also lossless compressed, that camera doesn\'t do uncompressed RAW. I\'ll update that page with that correction and include the average file size, which was slightly smaller at ~35MB. It is difficult to compare between cameras on continuous shooting tests. There are many factors that affect frames in 30 seconds. With enough testing it is possible to extrapolate based only on knowing a write speed and the camera behavior (write delay, fps, when it decides the buffer is full for a given image size/setting). I have enough data on the D750 to do this (including for several different image settings). From what I can tell the buffer size is about the same between the D600 and D750, the difference is in write speed where the D750 is slightly faster.
