The present invention involves an IC Package Similar IDE Interface Solid State Disk Module & Optimized Pin Design, in which the solid state disk module consists of a solid state disk module control, several flash memories, a power regulator; a low power detector and a short circuit preventing circuit; through link between signal position and data lines of the solid state disk and the IDE data storage a interface, data which are expected to be stored in the system is able to be written in the solid state disk module or read out by the solid state disk module; the link has a type of dual-in-line package which can be soldered directly on a PCB of the system so that the mechanical structure for conventional hard disk will be get rid of, resulting in high vibration resistance, small dimensions, therefore, it is very suitable to light type portable computer systems or industrial computer systems where requirements on data storage and vibration resistance are needed.
