OK I guess I have a solution now, I just called 3ware and spoke with sales.
On the 9650 se 4 port SATA cards, even if the card fails, they say that I could
use a different model card from them if the old card is dis continued;
because if the original fails, they designed it such that I could replace it with a different card.
I could even migrate a drive to a different motherboard-
and still read one of the mirrored drives.
For the 8006 series card, this is not the case, I would have to buy the
same model card, however I would be covered for at least four years,
because this card is still in production and probabally will be for another year,
and with the three year warranty I would be covered for at least four years
from purchase time if the card dies and I need a new one.
I need one of each card, a PCIe and an older design PCI.
