Not associated with the OP, but I don't think so. It really does return your data 25x faster than a disk-based DBMS. The implied reduction in durability from being in-memory is clearly stated up front.
Given that you can configure any DB to use extra RAM as a cache, and many datasets will fit in that cache, if I was a fact checker I'd give the "25x faster" rating at least a "partly false" rating.
