Excerpt: I have used Sandisk memory cards since 2004. They have always worked flawlessly, whether compact flash or SD. I stick with "extreme" class for cards that i use over and over again. For storage, or one time use, "Ultra" class is best value. On the Nikon D800, the 8g card holds about 240 large/fine Jpegs or 100 raw (multiply that amount by 2.2 if shooting in Dx mode). The card is fast. I shoot at any pace i want, single or full auto.
Pros: Great Value, Reliable Performance, Writes/Reads fast
Excerpt: The two cards I purchased are for use in Sony digital recorders I use to record video presentations, recitals and high school sports. The cards allow me to record over 2 hours of HDV or standard definition AVI files that I can import directly into my NLE.
Excerpt: I have two of these cards and both have worked flawlessly for stills and video on a 5D Mark II. I always format my cards before each use, and use a UDMA card reader for downloading onto my Mac. Never any problem, error message, or corrupt files. Happy camper!
