High speed data storage system

A high speed data storage system comprising:

• a plurality of hard disks;
• a first control panel comprising a first control chip and a first connector, and a plurality of first printed circuit wires electrically connecting the first control chip with the first connector being layered in the first control panel, the first printed circuit wires configured for transmitting control signals from the first control chip to the hard disks, respectively;
• a second control panel comprising a second control chip and a second connector, and a plurality of second printed circuit wires electrically connecting the second control chip with the second connector being layered in the second control panel, the second printed circuit wires configured for transmitting control signals from the second control chip to the hard disks, respectively;
• and
• a midplane interconnected between the first and second control panels at one side of the midplane and the hard disks at another side of the midplane;
• wherein the plurality of first printed circuit wires of the first control panel and the plurality of second printed circuit wires of the second control panel are arranged symmetrically with respect to each other, and an order of stacking of 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.
