I just bought my first SD cards (in prep for D7000) and am left with questions. The better card I bought was a Sandisk Extreme SDHC Class 10 200X 16Gb, I got a heckuva deal.
But it is labelled as only 30Mbps. I know the Compact Flash version of the same card is 60Mbps. I am a little disappointed in this because I know from experience my CF Extreme IVs at 45Mbps are noticeably faster in clearing my D300 buffer after a long heavy burst than the Extreme III 30Mbps that I own. Did I inadvertently buy an 'old or clearance model' Sandisk Extreme or is that it for now for SD card speed (aside from an Extreme Pro)?
I'm guessing this is an inherent limitation of SD as compared to CF. I would appreciate any guidance, haven't opened the box yet.
I also bought a class 6 16GB Platinum II 100X 15Mbps, my first Lexar, for video. I figure that should be good enough speed for video.
