In linux, I find this to be completely wrong. I have 15TB of software
raid 6 and the most load that it puts on the cpu is around 7% and
these are raid arrays that net over 200MB/s writes on single core
systems that are 3 or so years old.

In windows software raid performance sucks so you need a hardware card there.
