[Q]: Works great but is overkill for my point and shoot Olympus for photos. I got the high-speed card to be sure that audio will stay synced with the video. The 600x speed vs 300x speed makes no difference in 8GB Lexar CF cards that I use in matching Sony a700 DSLR's (e.g. five fps in bursts, but will slow down to one fps after 3 seconds, 14 frames total). I think this is due to the cameras buffer not the card performance. The Lexar 8GB 600x CF cards stay at the same capture rate as the 5 year old Lexar 8GB 300x CF cards, but that may be the 5 year old camera can not write at the faster speed. Be sure to read the manual to determine the maximum card size your camera will take. Most camera makers have pdf copies of the manuals available on their web site under "Support". I have a 2007 Ricoh at work that will not read anything bigger than 2GB. My 2013 Olympus will not read anything bigger than 64GB. The camera's maximum data write speed may not be in the manual. DSLR or Prosumer cameras can write to the card faster than lower priced cameras. High-speed cards (e.g. 600x or Class 10 for this Lexar) will work in slower cameras, but they will only store data as fast as the camera can push it.
