D200 write speeds...

    I got a job at the campus newspaper and they gave me a D200. Continuous shooting within the buffer works fine, but once the buffer fills up it shoots at around 0.7fps. This is with a Sandisk Extreme III CF card at 30MBps.
    Is there something wrong with the camera? I have RAW compression turned on and am getting 9MB NEF files, so shouldn't I be getting a little over 3fps?

    How many shots are you able to take before the camera slows down?

    I did a test with my camera (also a D200 with Sandisk Extreme III card) and this is what I got before the camera slowed down, shot at the fastest frame rate available (5fps?).

    22 uncompressed RAW
    28 full res JPG

    After these numbers of frames the camera slows to a crawl as the buffer is filled up. This is normal until the camera can clear some buffer space. As a comparison it is much the same as the RAM in your computer -both act as a temporary, very fast, storage space. Both a computer and camera slow down once this space is filled up as they can then only work as quickly as the next part in the process - the CF card/hard drive.

    Additionally, if you need to shoot constantly at such continuous frame rates then I think you need to think about how you are shooting your photos. I have only once filled the buffer on this camera in the 3 years I've had it, whilst shooting RAW.

    Hope this helps.

    I can take around what you're getting. I probably wont ever fill the buffer so it's really a non-issue, I was just wondering if there's something wrong with the camera because on my D40 I can still shoot at the speed of the memory card after the buffer's been filled.
