Pretty cool though, but an utter waste. Surely the bus is way beyond saturated at 5.2GB/s though? As you'd need to be running at 6GB/s bus speed to be able to take it, which I'm fairly sure that the controllers are stuck at 3GB/s due to the complexities of processing the data at a different speed to the speed it's talking to the drives. Hence the birth of 2nd Generation SAS and soon to be SATA 6G.
I may be wrong, but it's the impression I got from HGST on the limitations of SAS. 14 drives would be about it's performance peak I'd say!
