[QUOTE="WayneF, post: 235398, member: 12496"] Be careful what you believe on the internet. :) That article is only superficially echoing back the card advertising. It did not test anything in any camera. For example, it claims that the SanDisk Extreme Pro can write 95 MB/second (Sandisk advertises that), and probably it might do it in a fast computer USB 3.0 port, but [URL="http://www.robgalbraith.com/camera_wb_multi_page8e34.html?cid=6007-12454"]Gailbaith tested actuals[/URL] for that card in cameras this way: D7000 SD 24 MB/second writes D700 Compact 33 MB/second writes D800 Compact 61 MB/second writes (UHS-1) Technology is improving, and fast cards are faster than slow cards, and fast cameras are faster than slower cameras, and Compact cards are faster than SD cards - but camera writes are not likely near as advertised. Computer reads can run that fast if in a USB 3.0 card reader, which can be important when you are transferring a few hundred images. The newest cameras (including D3200, D5200, D7100, D600, D800) spec to support UHS-1 cards (ultra high speed). So for cameras that do, get a card (and USB 3.0 card reader) that also supports UHS-1. UHS-1 claims writes of 100 MB/sec, but the camera also has other things to do too, processing and compressing the image file, writing the internal buffer, etc. Card speed is not very important if writing one JPG file every now and then. A burst of Raw files becomes important. Card reader speed at the computer can seem important. And card speed is not important for writing video. Any old class 6 card is fine for video (except you may want the computer read to go faster). [/QUOTE]
