16GB CF cards for $69

    So I flew to Seattle recently, and my first stop off the plane was, of
    course, Fry's Electronics. I got a 16GB CF card for $69. (You can too -
    http://shop3.frys.com/product/5579540).

    The next morning, I woke up early thanks to jet lag. (I was up in
    Vancouver.) I figured I couldn't sleep, so I'd go take a few photos. I
    set up on a beach across from the skyline and started to squeeze off a
    few photos.

    "Why this is quite a bother," I thought, "this new card certainly is
    slow as hell!" It was filling up the buffer and writing to the card so
    slowly that I could only do 3 or 4 continuous shots at a time before the
    shutter button was disabled and the camera was catching its breath. I
    decided that I'd gotten what I paid for, and even though the card was
    labeled 233x it was a cheap dud.

    Then I got back to my hotel and started to look at the images I'd taken.
    I realized that instead of taking a series of JPGs in FINE mode, I had
    somehow set the camera to save as TIFF only. Voila! When your card is
    full of 35MB images, each image tends to take a little bit longer to
    read and write than a 3MB JPG does.

    IDIOT.

    Reflect on how far things have gone in a short time. I've hung on to my
    Coolpix 995 for 6 years now, and although it is still good for what little I
    do, one wouldn't really bother to set it to shoot in .tiff format, because
    it takes about 8 or 9 seconds *per shot* to send the data to the card. After
    the first time, I never bothered again! (Fine jpegs take about half a
    second, still glacial by 2008 standards, but I can live with that...)

    Your extreme case was the result of a combination of both the large files and
    the slow card.

    Go cheap on the card when you need a LOT of them. I go with the fast cards.
    My batteries run down before I fill a 4GB card. I have 2 4GB cards and have
    not used the 2nd one for photography, yet (it got used to load Linux onto a
    new computer, instead of wasting a DVD+R, and that's it), FYI, I reformat
    the card after storing all the photos onto a computer and make 2 backups.

  4. I bought a couple of Class 6 16Gb SDHC cards in Japan recently -- the
    first one (Green House) cost me about 65 bucks US, the second one
    (Adata) was less than 50 bucks. Both work perfectly fine in my camera
    (Canon A640) giving me a capacity of about 3900 pictures at best
    definition and quality or 120 minutes of 640x480 video at 30fps. I don't
    notice any effective speed difference when shooting burst between these
    cards and the 1Gb and 4Gb SanDisk Ultra II cards I was using previously.

    I have a couple of cheap (2 buck) pen-style SDHC card readers that I
    use as USB flash drives; one of them has the spare 16Gb card in it at
    the moment.

    When the card filesystem is (nearly) empty, writing is faster because the
    computer has fewer operations to do. Fill it up, and especially delete
    stuff and fragment it, and the effective speed slows down because more reads
    have to be done to place the new files.

    Smarter CPU programming can overlap writing the last picture while shooting
    the next. This will make things go faster, but once conditions fill up the
    buffer space, this doesn't help, and it gets just as slow.
