1TB/second is a benchmark number, and obviously it is trying to impress. This is already a purpose without further clarification, on the other hand it does not necessarily mean it can not have other purpose - which again looks an extremely expensive cluster for that purpose. And I do not see the reason to down vote except some one got hurt in the feeling with a fact. With the actually configuration shown, it is just not that performant nor economical, as I said in the reply, if you had read anything about it.
