[QUOTE="NIKONIAN_DREAMWEAVER, post: 399575, member: 36003"] I noticed you edited your post and changed the wording. We'd have to talk to a Nikon engineer or someone that knows the particular mechanics of the buffering function. Maybe one will chime in. I suspect that it is not true that the buffer has to completely fill up before it writes to the cards. All I know is the faster the card, the faster the fps (up to 6 or 7 depending on whether you're in DX or crop mode). The average/standard-speed (slower) Sandisk card that I was originally using when I first got my D7100, was giving me about 3 fps. [B]The card was clearly the bottleneck.[/B] I've heard a lot of folks complaining about the (D7100) buffer and fps. With the Sandisk Extreme Pro SD the camera meets factory spec's. With a slower card, it doesn't. [B]This is important:[/B] I read somewhere, awhile back, (I think the source was Nikon corp.) about the D7100 buffer speed. My memory is a little vague on it, but the general gist of it was that the buffer in the D7100 was much faster than the average (slower) memory cards. When you step up to the ultra-fast cards the buffer clears at a speed much closer to it's maximum capability. I'll see if I can find whatever it was that I was reading... [/QUOTE]
