You are correct, I prefer to use MD (with LVM on top). The main reason
(beside cost) is that if the card fails I don't have to get an exact
replacement for it in the future.

I'm planning on this case:
NORCO RPC-4220
http://www.newegg.com/Product/Product.aspx?Item=N82E16811219033

With six SATA ports on the motherboard, I need extra 14 ports. The
SuperMicro AOC-SASLP-MV8 card would be a good fit (times 2), but it does
not look like it works well with open source drivers (I use Debian).
As an alternative I'm looking at Areca ARC-1300IX-16

http://ncix.com/products/index.php?sku=37131&vpn=ARC-1300ix-16&manufacture=Areca

but it is double the price.

I'm trying to not use PCI-X motherboards, both cost and no future
availability.
