If you're looking to buy memory cards for the D7000, I *highly* recommend the SanDisk Extreme Pro 45MB/s UHC 1 card. It's blazingly fast with the D7000, which can fully leverage its speed. Just as an example, I set up my D7000 to do RAW 14-bit+JPEG Normal and use the second card as a backup (not split the RAW and JPEG between the two cards). I set it up in continuous high, and held down the shutter release until it slowed down, then watched the "write to card" light and counted until it went out. It took 91 (yes, that's a minute and a half) seconds to complete writing all images to the main card and back them up to the secondary card as well using a standard category 6 SDHC card. With the aforementioned UHC 1 card, I did the same test and it took only 17 seconds. Quite a big difference. Now granted, nobody's going to write RAW 14-bit + JPEG Normal to both cards when also using continuous mode on a regular basis, but it did allow for me to see the true difference. I cannot recall if I had sharpening turned on, which may have contributed to the big numbers overall as well, but the difference percentage-wise is what counted anyhow.
