Forgive me if I'm not reading you right, but are you advocating using
fake-raid cards if there are Linux drivers for them?

>From what I've seen in practice, and also from the general advice I've
seen in CentOS lists, I believe Linux RAID (based on mdadm) is
superior to any fake-raid, and should be the one we advise in the
Wiki.

If I were to decide, I believe the Wiki article should advise against
using any kind of fake-raid and use mdadm instead.
