I've been using this flash card in a new Nikon D700 camera for the last month. The D700 can write a full Nikon NEF format picture AND a JPEG version simultaneously if you so desire. I set the camera up to do this and took about 450 photos (that's 900 NEF + JPEG) shots over the course of a middle school wrestling match. Not once did the camera stall writing to the flash. So, no problems with write speed. I've shot, in total, over 3000 photos at various sports meets in the last month with no problems. I've also had no issues accessing the flash over an external USB Flash reader with my computer (Dell D620). By the way, helpful hint, some external readers are happier if you plug them into the USB port without the flash card installed in the reader. Once the reader is recognized by the computer, then plug in the flash card.
Performance test: Number of files 349, total size 751MB. Time to read from flash to hard drive: 110 seconds. 6.83MB/sec. Took the same file and wrote from hard drive to flash: 450 seconds. 1.67 MB/sec.
Finally, its just really cool having 2500 pictures or more showing on your camera's info panel with an 8GB card :)

I know SanDisk makes faster cards, but this is plenty for me and the price was right! Ya, I know about all the super rebate deals you hear about from Adorama or other retailers who offer 3 of these cards for a net price of $20 or so after huge rebates, but they make you wait forever to get that rebate and its in the form of a Visa gift card. I guess I need instant gratification and I don't mind spending my money with Amazon and paying more because I know I get the super service that comes with it. No strings attached. No forms to fill out. No time to wait.

I ordered the product and it was delivered on time. I use the memory in a Canon D-5 and in terms of response it is excellent. The memory formatted though you must have updated the D-5's software to have it recognize 8 gig of memory. No problems to date - I've had the memory for a month.

I just got back from Kenya where I was shooting photos for my work and also took a lot of personal photos while on a safari. This card was great! I didn't have any problems and never had to wait for the card to catch up to me. I took nearly 800 photos in RAW without having to fumble around swapping cards while bouncing along in the Maasai Mara. I highly recommend this card.

I bought this for my wife's Nikon D70 Camera. Sandisk has always provided us with excellent service. It was bought as an upgrade and it definately is fast
