Ultra high speed! I also use a high speed card reader!

Summary: I ordered this card when I ordered my Nikon D700 with battery grip. Works great at 8fps on my camera when I took photos at a truck race. Very fast upload to my coputer through my high speed card reader too. Highly recommended.
Summary: Great! Being that I recently purchased a Canon 7D and my RAW file sizes jumped from what used to be about 10MB on my XTi to about 25MB on my 7D, I needed a large capacity CF card to store more images in between image downloads to my computer. Used it at a small wedding recently and it was able to hold roughly 400 of my RAW images I took that evening. No problems or lag.
Summary: I needed a CF card for my new Nikon D300S, so ran out and bought the cheapest CF card I could find - a Core Micro 16GB. I was getting card read/write errors after firing off a few shots. I headed to the forums, and discovered a software upgrade for the camera that was supposed to fix some card errors, but not my specific error message. The errors persisted even after the upgrade.
Summary: In light of my recent upgrade from the old 5D to the new 5D Mark II, I thought I might need a faster card for the larger file sizes, and THIS IS IT! I'd been using an old Transcend 133x card which was fine on my 5D, even though the buffer would fill after 4-5 RAW shots. That didn't seem to bother me much since I mostly shoot nature/landscape and macro. This card makes me want to shoot action. It seems to write as fast as I can push the shutter.
Summary: I have used other brands of CF cards and have been disappointed. But I have never regretted any of the Lexar ones. Yes I used to get Walmart consumer grade 1 GB and 2 GB as they were so cheap and never had a problem with them (these 10 CF cards are still around if I really need them), but I now have 6 8GB UDMA 300X and one of the 16GB UDMA 300X and will never use anything else. Thousands of images with my Canon 5D with never a problem all over the US and in Canada.
Summary: The Lexar Pro 300x 16gb card is a must have for shooting video. I'm a video producer new to the DSLR world and the 16gb card is the workhorse of my memory card world. I have several 4gb cards that are great in a pinch, but they aren't worth using for longer shots and interviews. I plan to purchase more of these 16gb cards.
