Transfer speeds IS the difference. This will directly affect how quickly
your buffer fills up. Based on the technical guide, shooting uncompressed
NEF, the buffer can handle up to 16 shots of 75MB files. (I'm taking a wild
guess that the buffer is roughly 1GB based on this information) You can do
the math after that...
Shooting at 4fps will create 300MB/seconds in the buffer. Assuming you have
an SD or CF that writes at 90MB/s, it will take 3.33 seconds for that 1
second of 4 shots to be written to the card.
If you have a card that writes at 30MB/s, it will take 10 seconds for the 4
shots to be written to the card.
With a 30MB/s card your buffer will be filled in a little more than 3
seconds of continuous shooting.
With a 90MB/s card your buffer will be filled in a little more than 9
seconds of continuous shooting.
Math is a little loose but hopefully you get the point. |

再说，这就是民科，这些机器都有缓存。操作快不快就看cpu和缓存。写盘次之。
我给Sony hX9v上了很快的sd，操控还是慢的跟屎一样，就是这个道理。

还有cache?
我觉得这不民科，就是这回事

反正咱业余人士3秒连拍的机会几乎是0。30MB/S卡应该够了。容量大是关键

即使一般拍体育，连拍1秒也够了呀。
