there are two of them :-)

True.

and I have no control over the file system used by ma cemeras and
camcorders :-(

True.

if not I would like better ext2 :-)

Actually... these flash devices (not SSDs) are optimized for FAT. The
start sectors of the stick or card get smaller actual sectors (not the
proper name, true), because in that area there are much more writes;
for each file that changes something, there is a corresponding change
in the FAT, the directory table, or both. So they make that region
more resilient to multiple writes.

I had a link that explained this.

Found another one: <http://lwn.net/Articles/518988/>

There is a mention in the comments (by the article author) about this,
and that f2fs uses the same region.
