That's so-called "fake RAID": the actual mirroring is performed
by a driver which uses CPU.
The main difference between fake and real RAID controllers is
very simple: if it supports RAID level 5 - that's real RAID,
otherwise it most likely is a fake one.

Yes, and that's much better than using some hardware-dependent
code: if you have some trouble with the HDD controller, you don't
need to find a similar model from the same vendor - instead, you
can simply connect your drives to any other controller and get
the array running.
