Well the correct translation for "Laufzeit" is runtime and not latency. But thank you for that hint, I'll change it to "gesamt Laufzeit" to make it more clear.

In all tests I wrote 1GB and looked for the runtime of that write process. So "latency" on your diagram means total time to write 1GiB file? That is highly unusual meaning for "latency" which normally means time to perform single IO. If so, you should better rename Y-axis to something like "total run time". ��.n��������+%������w��{.n�����{����n�r������&��z�ޗ�zf���h���~����������_��+v���)ߣ�
