Sort of, though its not raid0. It will balance the writes across the
members of its storage pools. So in your 3 disk zpool, the writes will
initially be spread across all 3 members.

When the zpool gets very full, writes may go to one device more than
others due to space requirements.

Yes and no.

Some of the data will be written to other members of the zpool, but
the majority of the file will be written to the newly added disk. I
think that some space will be reserved for the ZIL on all members, so
there would be a little less than 400 MB written to the existing
members and the rest written to the new device.

I did a quick search for references and could find any, so take this
with a grain of salt.
