An exemplary high speed data storage system includes hard disks, a first control panel, a second control panel and a midplane interconnected between each of the first and second control panels and the hard disks. Each of the first and second control panels includes a control chip and a connector. First and second printed circuit wires corresponding to the hard disks are layered on the first and second control panels for electrically connecting the control chip with the connector, respectively. The first printed circuit wires of the first control panel and the second printed circuit wires of the second control panel are arranged symmetrically with respect to each other, and an order of stacking circuit layers of the first printed circuit wires of the first control panel is the reverse of an order of stacking of circuit layers of the second printed circuit wires of the second control panel.
