Certainly, but f2 write performance is supposed to be even worse than
n2 even in theory. Maybe I'll try it anyway.

The 3ware 7506-8 *is* a hardware controller and it quite obviously
does *not* have this ability, at least not for raid10. One can just as
well use the 3ware as a plain 8port controller and md over that,
doesn't make much of a difference. I find that interesting.
