The problem with the chipset is that the fake raid breaks under load
for some subset of users and trying to debug the file corruptions can
be impossible from the OS side. So you end up with a circle of finger
pointing where the user points to the OS manufacturer. The OS
manufacturer points to the hardware. The hardware will point to the
user for using the hardware outside of its specific 'recommendations'
which you thought was a EULA. After a long set of time.. no one is
happy and a lot of money/time was lost on something which can't be
fixed. So the hardware gets dropped from the OS vendor's supported
line to stop the circle. It doesn't make the customer any happier..
but they weren't going to be anyway.
