Solid state disk array

The utility model relates to a solid state disk array, which comprises a box body and a cover plate, wherein a solid state hard disk array unit is arranged in the box body and consists of a primary function PCB board, an interface PCB board and solid state hard disks; the interface PCB board is arranged vertically, and one side of the interface PCB board is connected with the primary function PCB board, while the other side is provided with joints at intervals for connecting the solid state hard disks; a card slot for the corresponding sleeve joint with the solid hard disk array unit is arranged in the box body; and a bulge for bearing the solid state hard disk array unit is arranged in the box body. The solid state disk array has the advantages that: the array is directly configured with an array realization primary function PCB, interface circuits connected together in a matching mode are connected into a plurality of the solid state hard disks in cascade; all components are uniformly arranged in the box bo
