PURPOSE: A continuous data protection system with an SSD(Solid State Drive) is provided to improve an I/O(Input/Output) quantity and I/O speed of data and commands by emulating a high-speed SSD to an SCSI(Small Computer System Interface) device by using an SCSI drive. CONSTITUTION: An SSD controller(111) includes a flash controller controlling an interface flash memory for communication with a host and forms a flash memory array into a disk drive. An FTL(File Translation Layer)(112) converts a data writing/reading request to be matched with the basic operation of flash memory and adjusts a data unit difference between an OS(Operating System) and a flash SSD. A block device driver(113) is formed in function sets controlling a device in order to deliver data. [Reference numerals] (111) SSD controller; (112) Flash conversion interface layer; (113) Block device drive; (114) File system; (115) Application program; (131) SCSI driver; (132) Device drive; (133) File system; (134) Application program
