Rob galbraith has posted the CF memory card write speeds of the Nikon D200. The data in the table below was derived by timing how long it took the Nikon D200 to write out 31 JPEG Fine and 21 uncompressed RAW .NEF photos to the card. Timing commenced when the camera’s card status light illuminated, and stopped when the light went out. Each test cycle was performed 3 times (if the card’s capacity allowed for that) to ensure accurate results.

For example, the SanDisk Extreme III 1GB SanDisk has a write speed of 7.090MB/sec at Large Fine JPEG format and 8.173MB/sec at RAW format. The SanDisk Extreme III 2GB SanDisk has a write speed of 7.235MB/sec at Large Fine JPEG format and 8.419MB/sec at RAW format.
