Yes, that's correct. Buffer sizes are also all over the place, so if you want to shoot continuously, you need to pick carefully. Check https://www.fredmiranda.com/forum/topic/1856860/0 for a thorough analysis starting with the Sony A9iii (which can fill the buffer incredibly quickly with its premier feature, the 120fps 14-bit raw output global shutter). Deeper in the thread compares to the Nikon Z9.
