SD card: 150X or HC class 6, or HC class 6 150X?

    An explanation of the real world differences using a K10D, in fairly
    frequent burst mode but not heavy duty bursting (usually under 10
    continuously) would be very helpful. All the references I can find
    are all pretty cryptic as far as this goes. Sometimes figures are
    maximum or minimum, or constant or potential...

    Also in these searches I see posts claiming that some 4 GB 150X non HC
    cards are kludged to attain this rating, and have higher corruption
    rates. To stick with 2 GB if 150X and non HC. Hooey? Hard to tell
    about the HC card reviews because it's clear some people bought them
    for incompatible hardware.


    Thanks for any experiences good or bad with high speed, at least 4 GB
    SD cards, especially in the K10D.

    The class stats are for sustained speed, which don't say much about
    how well it serves in a camera when it's not relying on sustained
    speeds, which it usuall isn't. Tests show that cards in the same
    class aren't necessarily consistant in general responsiveness in
    cameras, but it is a guarentee of at least something.

    I've seen lots of posts from people with problems with 4 GB non HC SD
    cards ofcertain brands in cameras, because they use a kludge in
    addressing to get the larger capacity.


    This thread has some explanations:

    Unfortunately, Transcend, which had always been my go to for cheap and
    reliable 1 GB SDs, seems to have not hit the mark with compatability
    with their non-HC 4 GB fast SD cards, according to user reviews on
    price sites, though I'm sure they're not alone.

    Generally speed is an issue for download time, not for keeping up with
    your camera.
