I was wondering what sequential speed should I expect from a RAID controller that has 1 x MiniSAS 6Gbps port.

In the product details -> Data Transfer Rates: Up to 6Gb/s per port

Does this MiniSAS port has 4 x 6Gbps link or just 1 x 6Gbps link? Should I expect 750MBps sequential speed max or 4 x 750MBps speed max?

Thanks
