Perhaps, the question should be how one could mix them to get the best of both worlds instead of going to either extreme.
In the specific case of a 3320 I think Jonathan's chart has a lot of good info that can be put to use.
In the general case, well, I hate to say this but it depends. From what I've seen the general discussions on this list tend toward the "Make my small direct connected desktop/server go as fast as possible". Once you leave that space and move to the opposite end of the spectrum, a large heterogeneous datacenter, you have to start looking at the overall data management strategy and how different pieces of technology get implemented. (Site to site array replication being a good example.) Thats where I think you'll find more interesting cases where raid setups will be used with ZFS on top more then not.
There are also the speed enhancement provided by a HW raid array, and usually RAS too, compared to a native disk drive but the numbers on that are still coming in and being analyzed. (See previous threads.)
