Well the "correct" way to build the NAS would be to install DF on two
embedded SSDs and have data on regular HDDs as Mehmet suggested. One
would want to have RAID 1 on those two embedded SSDs or two have HAMMER
mirror stream. Unfortunately AFAIK current installer supports neither.
On the top of it HAMMER slave drive is read only so it would take human
intervention to have a "graceful" failover in the case one HDD dies. 
My understanding that HAMMER2 will not have that problem as the slave
will be writable. 

Yes DF could be molded into wonderful NAS product with little bit of
corporate backing :)
