How long will photos stay on a sd card before going bad?

I've actually seen the digital bits leaking out of the tiny holes on the
flash card if it was left in the sun too long.

If you write them to the media and leave it? A LONG time. If you're
constantly rewriting, it will wear out.

Just found an article (sorry in Russian) about flash memory and its
limitations.

If anyone is able to translate that into English it would be good.

I think the SD-card spec says 10 years iirc.
Not that anyone should try the roulette game..

I suspect the longetivity of the 10000'th write isn't the same as for
the
10'th one. No bias in to either one.


Since the cards haven't been out long enough for meaningful empirical
data, it is just a guess, anyway.

Well, it could be an educated estimate, which is remarkably much better
than a guess.

I should think that there are ways to make the guess better, but the
actual results will probably be better than the guess, and vary
considerably from card to card. Storage conditions will probably also
enter into the final consideration.

Some cameras support copying between cards if you have nothing else.
That's interesting. Which ones? It could be very convenient.

My Olympus E500 can copy between the XD cards and the CF cards.
My Pentax Optio WP can copy between internal memory (only 12 Mbytes though)
and the SD cards.
What would be nice is a camera that can read/write USB memory sticks. It
should be easy as many can drive USB printers.


Many cameras have internal memory as well as card slots, and these can
often copy between memory and the card (Kodak does this). The internal
memory is quite small, relatively, with sizes from 8 to 32 meg, but some
copying is allowed.
