<P> A solid - state drive ( SSD ) is a solid - state storage device that uses integrated circuit assemblies as memory to store data persistently . It is also sometimes called solid - state disk ; the word `` disk '' is inappropriate since SSDs do not have physical disks . SSDs primarily use traditional hard disk drive ( HDD ) interfaces , such as SATA and SAS , greatly simplfying usage of SSDs in computers . Following the initial acceptance of SSDs with HDD interfaces , new I / O interfaces like M. 2 and U. 2 have been designed to address specific requirements of the Flash memory technology used in SSDs . </P>
