Now we see through a glass, darkly...

Just because a card is capable of writing "up to" 200 MB/s or 250 MB/s doesn't mean the camera it is being used with can write that fast. It also does not mean the card is capable of sustained writes at that speed. The 'Burst Speed' metric is based on how fast a particular camera will write to a particular card, not on the card's potential top speed. If the camera is limited to about 170 MB/s, it matters not how fast the card is.Interesting but, it didn't include two very fast cards. Pro Grade has a read speed of Up to 250MB/s and a write speed of Up to 200MB/s. The Delkin Power SD card has a Read speed of 300 MB/s and a write speed of 250 MB/s. I am sure that there are other cards out there too.
