"fakeraid" is software RAID with hardware support. That is what you
have. True hardware RAID does all the work on the card.
See here:

In a sense software-RAID is also "fakeraid". The idea is that
the OS still sees individual disks, i.e. it is not an "array"
in hardware. One other problem with fakeraid is that is usually
cannot be accessed with different OSes. That issue does not exist
with true RAID, since all management information is hidden
from the OS by the controller.
The vendors just like to call their hardware supported software
RAID "hardware RAID", since it sounds better. But essentially it
is a marketing lie.
