Well I ordered this card to see if I could improve the "recording" speed of my wife's 2 year old Kodak DX7630. I had been using a couple of 512MB cards, also a couple years old, which would take 7-10sec between photos.
I got the new card and tried it, no big change!? I then plugged the card in to my card reader on my Dell to see if there was a big speed difference between it and the old cards. Nope!?
So now I get online and start checking. I find a speed utility, "HD Tach", and check both old and new cards. Results: 7mb/s for my 2 year old cards, 13mb/s for the new one. This is far below the 18mb/s (120X) rating (150kb/s x 120).
So I start checking info online (which I should have done earlier) to see if I'm missing something. It appears that you better have a fairly high end and/or new camera to get the best results from these "high speed" cards. The speed bottleneck may be the hardware on the camera, which I think would take some deep research to determine on Kodak cameras. I also checked in to why the card reader wasn't moving data very fast. Turns out you need a "high speed, USB 2.0" card reader to get 18mb/s. An ordinary USB 2.0 reader will only do around 66x or 10mb/s, as far as I can tell.
So what did I learn (and you should know): Your camera may not be able to move data as fast as this card, check first. It might be able to use it, but that doesn't mean at full speed. Your card reader probably won't move data as fast as this card can. So in the end, maybe I will get a new camera and be surprised at the speed, but right now I'm not really noticing a big difference, my bad. If I had something that would read/write at the max speed of the card, I would probably be impressed!
Just a note, check my math and do your own research, I was wrong once before, ;)
