It might help you to figure out whether individual OSDs do not perform as expected. The amount of data written is limited (but there's a config setting for it). With 1 GB as in the example above, the write operation will probably be limited to the journal.
Thats perfect, thanks Burkhard, it lets me compare osd's and configurations.
