It's hard to be precise without more precise data, Patrice.
Basically, an 80x card has the potential of transferring data at
about twice the speed of a 32x card, but that potential is
constrained by how fast the camera's data bus can support. The *ist
DS body can just about use the full potential of a 60x card's write
speed, cards faster than that will not appear to be any faster when
used in the DS. Depending upon how slow your current cards are, you
could see anywhere from substantial to relatively minor gains in
write speed, in camera, with an 80x card.
I know that comparing my 45x PQI card to my 60x Transcend or Sandisk
Ultra II cards, I see about 15-25% reduction in write time on bursts
of five frames. And comparing an old 32x Sandisk card to the Ultra
II, the difference is closer to twice as fast.
The differences are larger when it comes time to upload to the
computer. With a good USB 2.0 card reader, the Ultra II cards achieve
transfer times in the [EMAIL PROTECTED] range where the slower cards
take correspondingly more time to deliver data. A full Ultra II 1G
card transfers its data to hard drive in about 2.5 minutes, where
that same old 32x card takes just shy of 5.5 minutes.
If you're more of a "one at a time" picture taker, the difference in
performance in-camera might never be noticeable. The camera's
buffering will just perform the writes while you go on with taking
other pictures.

For my info, can someone give an idea of write times for such a 80x
card with a *ist DS? I only have cheap/slow cards now, and I'm
wondering if I should "invest" in at least a few fast ones, as I shoot
RAW.

I have one Transcend 1G SD card, rated at 60x. it's been reliable but
is not as fast a performer as the Sandisk Ultra II 1G SD card, also
rated at 60x. The difference is noticeable but not that huge a
difference. It was about 20% less expensive.

Transcend has been around for a while. Friends have been using
them for
years, and that's why I bought mine + the price was nice for the
features.
IMO, they're as good as Lexar, Sandisk, or Kingston. Comes with a
five
year warranty.

I have never heard of transcend before. Is this a reliable brand? I
don't want it to crap out on me after a whole week in Europe or
anything like that.
