Want to know the buffer size on the 5SD mk3...

... and/or the number of full res raw files it can hold. Wondering if I usually shoot a max of six shot bursts, does the card write speed even matter?

At 6 shots it doesn't matter.

 

See:  http://www.learn.usa.canon.com/resources/articles/2012/eos_understanding_burst_rates.htmlp

 

The conservative estimate for the buffer size (in RAW mode) is that the buffer will hold about 13 shots before the camera has to wait for data to write out in order to clear enough buffer space for another shot.   I've actually tested this with my 5D III and have found that in practice the number is a bit higher -- having about 18 shots before it slowed down due to buffer limits.
