Greetings,The important number for emptying the camera buffer is the WRITE speed of the SD card.I picked up the Extreme Pro SD (90 MB/s) and it makes a huge difference in the continuous shot mode.B&H sells them for approx $2 a Gig. Kind of expensive but I think worth it.Bottom line: the faster the write speed, the longer before the buffer fills up. Balance that with the price so it fits your needs.Hope this helps.
