SanDisk SDCFX3-004G-A31 4 GB Extreme III CompactFlash Card (Retail Package)

Planning a trip, I am stunned to think that this card allows me to carry the equivalent of over 20 rolls of film for my Nikon D-70. Writes fast, works great. And it freshens your breath!

It's Difficult to make a drawn out, detailed review for this product.
Simply because its exactly what they say it is: fast, accurate , reliable data storage. Ive used it in the snow , and in the blistering Arizona dessert, pared with my Xti. I have NEVER had any issues with it, ever. So far I have had 3,000 + images taken, most in raw. The box came with a good quality key chain to hold another memory card and a well built plastic case to hold it.
Should I ever need another memory card , or need to recommend a card to a friend , this will be the first , and only memory card on my list.

I have had this memory card for nine months. It's the best that I have owned. It functions flawlessly with my Canon 40D. Excellent speed. I can't say enough positive things about this excellent product. I take it out of the camera and insert into a reader, to take photos off the card. I have never had a problem, after many thousands of photos and numerous insertions into the card reader and the camera.

I only had it for about a week, and so far it's been fast and reliable, the only thing I wish it was a bit cheaper.

The Olympus E-500 is known for being able to write to CF cards very fast. This card - as advertised - is very fast. I chose this card specifically because of the camera's ability to write fast and my desire to use RAW format - which on this camera is about 13mb per picture. While I don't use it for sports or drive mode, it easily keeps up with multiple shots in a row. The 4gb capacity also helps with so many big files! It's the perfect card for this camera.
