I own 4 of the 8GB version of the cards and couldn't be happier. I strongly encourage you to test the cards yourself as you will find wildly different opinions here. Buy some cards from some place that allows returns, borrow from a friend, or something - spend a few $$ on shipping costs to save you real $$ and time in the long run.

The most dramatic performance increase that I noted was the time to transfer the card's contents to my computer. A USB 3.0 card reader is a must for ultimate performance - the USB 2 readers max out at speeds lower than the card is capable of.

I went with the UHS-I 95MB/s cards because the price difference was negligible to the 45MB/s version at the time I bought them. Note that different manufacturer's cards perform differently, so you really must do your own testing to get a feel for what is possible.

Your shooting needs also matter - are you shooting action of some kind where you need the maximum performance and need to optimize the D7000's capabilities (Just can't afford a D4, right?)? Do you want the fastest transfer time to read all the cards you shoot? In other words - why does speed matter to YOU? If you want the maximum performance from your D7000, buy the 95MB/s cards - maybe you can compromise and get the 8GB version at half the price of the 16GB you are looking at -- do you REALLY need 16GB cards?

Your choice of a reader is important -- in a previous post I stated:

"I had to return my Delkin USB 3.0 reader (Model DDREADER-42) because it would not reliably recognize the new 95MB/s Sandisk cards. (SanDisk Extreme Pro® SDHC™ UHS-I Memory Card - 8GB SDSDXPA-008G-A75). I returned it to the store and purchased a Sandisk Imagemate Model SDDR-289-A20 to replace it.

Plugged into the USB 3.0 port of my computer and using Nikon Transfer 2 as the transfer program, I was able to move 100 12-bit RAW files (average size or around 14.5 MB each) in just under 23 seconds. I timed the transfer from when I first clicked the transfer button until the transfer queue read 0."

You're on the other side of the world from me and I do understand that availability of products may be different than what I experience in the US. Best of luck with your purchases.
