I bought two Sandisk Ultra 16gig 30MB/s cards I have been using the Sandisk Extreme at 95MB/s and the Sandisk one that is 45MB/s I got the two 30's on sale because I need more room to keep shooting a big project. The good thing is they shoot fine but shooting auto bracket it takes more time than either the 95 or 45 cards. enough to notice This 16gig card when full takes about 24 minutes to download off the card to computer on my laptop. That is why it is important to have extra cards. If during a shoot you fill your card, it will take 24minutes before you can shoot more. Keep Extra on hand and have at least two empty cards with your camera if on a big shoot. I bought a 32 gig card but that takes 50 minutes to download when full. So I am happier with the 16 gig size and will stick with those. All in all they are good cards. I shoot lighting pictures which are time exposures and after each shot it takes many seconds before you can shoot again, so a 95MB/s is what I use for that. Just out shooting landscape and everyday or even Portrait these work wonderful if you have enough of them on hand that are empty. Shooting Raw at 24.7meg and a jpg with it does slow down or speed up the camera due to the card speed. If you only shoot jpg during a shoot you may not even notice the difference between a 45MB/s card and these 30MB/S cards during shooting. So in the end they are quite usable. But I would not go below a 30MB/s card if you are shooting RAW files. Make sure you read the specs. some off brand Cards say a high number but you don't know if that is the Write speed or Read speed. some cards the Read speed is half that of the write speed or the other way around. Get a card that has the same number for write and read speed. Good luck and happy shooting.Read full review

Really, what is there to say. It is a solid state memory device for my Nikon camera. It works as it should and has high transfer speed. SanDisk is a reliable, well trusted brand.
I bought this product because it holds alot of memory and my mother loves to take lots of pictures. I love the SanDisk product, I probably won't buy another brand Thank you Key00west
Best of the bunch for the price. Fast and reliable for HD video and pics; use it with a digital SLR; beats the other brands that claim to be rated at this same speed.
