It's not doing anything else on that drive. I think it would be faster but the option CONFIG_MULTICORE_RAID456 was switched on in this kernel, so there are lots of async processes fighting each other (190 of them on this system).
Oh it's this one then. I read it has already been discussed here... you really need to remove the multicore implementation: it's experimental as of now and *much* slower than single core. I don't know why the your distro maintainer has activated it. What distro is that? Someone should probably tell the maintainers to disable it by default. I think all your problems will go away if you can recompile with multicore off.
