I agree that you are almost always better off with Linux software RAID, compared to onboard "fakeraid". Typically, Linux software RAID outperforms those fakeraid controllers and you have easy software access to the health of the array and you an initiate rebuilds, change drives and such fairly easily with software RAID. The top reason for me, however, is the portability of Linux software RAID. If you have a motherboard completely die, you can move a Linux software RAID array to a completely different machine, with very different hardware. You typically cannot do that with "fakeraid". This is a very real-world issue that I've run into several times.
