The main difference is that the sample code in the reference
is just sample code. It shows you how to read the uploaded
file through a stream. This is more flexible than writing it
to a file. Of course it's simpler to just call write() if
you really want to write it to a file.
In fact, the write() method is more efficient as it will try
to use a file rename as long as possible.
