I am comparing two rackmount server chassis (Norco RPC-4220 and Norco RPC-4020, FWIW), which are identical except for the backplane connectors. One has 20 SATA connectors and the other has 5 Mini SAS (SFF-8087) connectors.
Is there any advantage to having 20 separate SATA connectors? I haven't come across a controller with 20 SATA connectors, so mini SAS breakout cables would be needed (I think) and not to mention all the extra cables to tuck away from the fans. Would an application actually prefer or need individual SATA connectors over the more advanced SFF-8087 connectors?
Does one connection method offer any advantage, such as performance, or is it really just a preference determined by the storage controller choice?
