Blade storage device

The invention provides a blade storage device and relates to the field of data storage. The blade storage device comprises an FPGA processor and a storage array pool provided for a bus of a high-speed serial bus card; the FPGA processor comprises a high-speed serial interface processing unit and an NAND controller; the high-speed serial interface processing unit is connected with the bus of the high-speed serial bus card; the NAND controller is connected with the storage array pool. By the use of the blade storage device, the problems of low reliability, low access speed and low requirements on work environment are solved, and a blade storage is high in reliability, high in access speed and low in requirements on the work environment, and multiple blade storage devices can be quickly and conveniently made into a high-capacity blade storage system.
