    I have an old 256MB compact flash card for my Canon EOS300D but I think
    its too slow (not to mention not very large capcaity). I was looking
    at upgrading to a new 2GB card and see that there are a lot of
    different speed cards. I was going to opt for the top 133x speed but
    then thought to myself, "does the camera utilise this speed to its
    fullest?". So basically is it worth spending the money to get the
    fastest card or will a slower one be just as quick in practice in the
    camera?

    Thanks
    Allan

  2. Can't find the 300D on the site but this should give you an idea
    http://www.robgalbraith.com/bins/multi_page.asp?cid=6007-7699

    The faster memory isn't always faster in the camera. In reality it's
    unlikely to reach anywhere near the maximum speed on a X133 card when
    writing images. may be more noticable when copying to your PC but
    that's about it.

    The 300D uses Canon's PREVIOUS generation processor (read: slower).
    Therefore, in YOUR camera, the "standard" card would probably be just as
    "quick" as a faster card.

    The value of a faster memory card would be if you used a card reader to
    transfer the data to a computer, and then it would have to use USB 2.

  4. There several reasons why a faster card is useful, including:

    1) a fast reader will allow faster downloads

    2) Eventually, when you upgrade cameras, then you have a
    fast card to use in the camera.

    3) The speeds on the Rob Golbraith site
    http://www.robgalbraith.com/bins/multi_page.asp?cid=6007
    are for empty cards. As a card fills up, speed drops,
    so a faster card has better performance. See:
    http://www.clarkvision.com/imagedetail/compact_flash_card_speed

    I buy the largest, fastest cards I can afford.

    Thanks for the input guys. It looks like the Canon EOS 300D uses an
    old interface so burst speed will not benefit from ultra high speed
    cards however downloading the images to the PC will benefit. The
    contents of the card play a part too, however I think this may be down
    to fragmentation of the file system. Since I use RAW at all times and
    regularly clear the contents this shouldnt be too much of an issue. I
    think with this in mind I have found a 40x card at a local shop (2GB)
    for £32.00 which seems good - there are cheaper online but once P&P
    gets added it doesnt seem worth it. This is unless anybody can
    recommend a specific card from a specific location?

    Many Thanks
    Allan

  7. The speed drop shown on my web page has nothing to do with
    fragmentation. Cards were fresh formatted and a series of
    files written. If you delete in camera and cause fragmentation,
    speed will drop further than shown.

    No. That camera will not benefit from the speed. However when you put the
    card in a reader it will move files very quickly.

    I buy SanDisk Ultra II 1 GB cards. Images transfer fast to my PC.

    Seconded, based on the Rob Golbraith site, I upped from a Blue Sandisk
    (one of the slowest cards out (0.75mbps)), to an Ultra II which doubled
    the speed in camera (1.4mbps), anything else gained only marginal
    improvements at much higher % cost increases.

    I also picked Sandisk going on user reliability reports on some of the
    no name cards available.

    Allan,

    I recommend taking a look at transcendusa.com. They have very good
    prices on 80x compact flash (and other) memory cards. I bought a 2GB
    SD card for my Nikon, and it works very well, for about $37.
