Solid-state drive
A solid-state drive (SSD) is a data storage device, typically used in a computer. It uses flash memory to store data even after power is turned off. SSDs are designed to access data in the same way as traditional hard disk drives (HDDs). An HDD can usually be directly replaced with an SSD. Most SSDs use the SATA interface, the same as what HDDs use. Some SSDs also use other interfaces for other devices, like servers.
