consisting of a control unit and a storage unit (FLASH chip, DRAM chip). The specification and definition of the interface, function and usage of the solid-state drive are exactly
the same as those of the traditional hard drive, and the product shape and size are completely the same as the traditional hard drive, but the I/O performance is greatly improved
compared to the traditional hard drive.
