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.
