I have done this 5 to 10 times as at work I have > 50 drives in raid
(5 and 6) at the moment (10 to 15 TB). On promise sx8 cards this
worked 3 to 4 years ago with early 2.6 kernels. However in the last 2
years  I have successfully done this with $14 4 port PCI  SATA cards
and also nVidia nForce 4 motherboard sata ports.
