Ok, they are not all the same...there are extensive tests out there demonstrating the differences. If you need speed (to shoot continuously, record video and transfer to your computer quickly), do your homework. I did a bunch and went with a pair of Lexar 32gb 800x cards for my 7d and have been happy. I've got over 50,000 images on each of them with no issues.

FYI, Lexar use NAND from Intel/Micron, controller from SMI. Unless you shoot RAW HD video, which requires you mod your canon body with magic lantern, there is no need to be faster than Class10, which is a 10MB/s write for a specific data pattern.

Video doesn't require a fast card. Anything over about 8 MB/s will be more than enough.

Video require certain class speed that is specified by your camera. Class speed is NOT sequential write speed.

Having that said, you can NOT have slower sequential write than Class speed, meaning a card that capable of 8MB/s sequential will NOT meet class 10 for sure. The opposite is NOT true, meaning you can have a card capable of 40MB/s in sequential write but can't meet class10.

I only use Sandisk CF and SD, have been for years, IMO they are top notch.

The Extreme Pro CF cards work great.

Note that the thread is about CF cards, which don't have the 'ClassX' system.

An important factor for me is fast transfer rates card to computer. I rather gather this isn't so important to most people.

I have used Sandisk, Transcends, and Lexar and the only one I have had problems with is Lexar. I would buy at least 16gb but recommend 32gb. As the newer cameras have more mp per shot and shooting raw I hate having so many flash cards that is why I would recommend the 32GB cards. Buy the fastest you can afford, this is because future cameras will have faster processors and the slower cards means slower shooting. I have the new 5D MK III and I can tell the difference between a 600x card and the new 1000x card. The 5D MK III writes to the 1000x card much faster which means more shots before filling the buffer and the speed in writing to the card and clearing the buffer. On my 7D I do not notice any difference between the 400x, 600x or the 1000x cards. When doing video I usually use the 600X or 1000X cards with no problems.

Thanks Talaska. Good to know real world experiences with the 5D Mark III and differences with the 600x and 1000x.

I have always used sandisk. Buy them from a reputable dealer - there are counterfeits out there.

Let's get the debate going.....Lexar, Transcend and Sandisk seem to garner the most support. None are perfect....i got 2 buggy Lexar 1000x UDMA 7 cards. At first they were buggy....gave error codes early on when I first got them. Annoying as they were so expensive. Funny though, they have settled down and not thrown a code for months now.

I use mostly 16 gb cards....two in the camera and two more in a little holder on the camera strap. I do have one 32 gB Transcend card too, works fine.

I'm late to this concersation, but what do you mean by "throwing a code?" Did an error code Pop up on your dslr screen? Or did you plug them into the computer and test them?

You get what you pay for, I personally stick with San Disk Extreme Pros but there are plenty of other good brands around as well. Stick with a brand that backs it's own products, there are cards that come with 10 year warranties (Panasonic Gold).

Best way to safeguard your photos is get a camera with dual card slots and write to both at the same time.
