Without sync option it is not writing into disk, it is just writing into a

Always use "sync" on removable devices otherwise you are risking toloose data
if the device is removed.Not if you unmount it before removing, as far as I know.
And you would have to wait before it is unmounted. In case of sync you can
unmount quickly.
When this disk is mounted with sync, writing to it is unacceptably slow
(20-30 kB/sec, > 4 hours for 500 MB file). Without sync option it is
~40MB/sec.
Without sync option it is not writing into disk, it is just writing into a
memory buffer.
In any case, could you please explain where it is defined?
There is no explicit rule in udev, at least I could not find it. I
understood that kded module is involved, but do not know the details. Is
there any configuration I could change, or is it kind of "hard-coded"?
