There is a finite number of times that a particular memory location can be
written to before it electronically wears out. But in most memory devices
I have seen stats on, this number is somewhere around 100,000 times or
more. Erasing an image removes the index from the file allocation table
(FAT) but does not overwrite the actual memory locations. A Format does.
So yes, formating instead of erasing will wear out the card faster, but
unless you are a very prolific photographer the difference between 50,000
and 100,000 uses is probably not a big problem.
Having said that, my experience has shown that my camera and equipment
seems to not have a problem with a card that just has had the images
erased, instead of a full format. So that is what I do. If I begin having
problems with capacity not coming back to full, THEN I do a format. But
that is me, and my equipment. Either way is ok.
