The answer to Larry's question depends on several things besides the model of the camera. 1) Are you shooting RAW, JPEG, or BOTH? 2) What is the write speed of the SD card? The purpose of the buffer is to save an overflow of information that needs to get written on the card. So the amount of info being written (#1) and how fast that gets accomplished (possibly bottlenecked by #2) are going to be a factor.
I recommend that the only way to test this is to put your camera on Manual and set the internal intervalometer for the maximum number of files you can get on your size SD card and try your minimum (like 3 seconds, which would give you 20 frames per minute). Let it go while it is sitting on your desk and see if it stops at some point, or is able to shoot the whole 500 or 900 frames without pausing or stopping. Unlike continuous frame shooting, where you fill up the buffer fast (after X exposures at Y frames per second), If you total write time is 3.1 seconds and you are taking an exposure every 3 seconds then .1 second per frame is being buffered. Eventually that will add up to to a full buffer, but it may take a LOT of frames to get there. Still you want ZERO frames to get there. Google Time-Lapse calculators for some useful ways to manipulate your values to make sure that you can also save the entire duration of exposures on your size of SD card.
