It makes no difference in speed if you use DAS cabling or SAS with
a concentrator. With DAS you have a "explicite" (double) ring 
typology. With SAS and a concentrator you have "implicite" ring 
typology, as the concentrator connects all the stations internaly 
to a ring. And you can mix DAS and SAS cabling.
