What is SSD(Solid State Drive)?
Solid-state drive (SSD) is a solid-state storage device that uses integrated circuit assemblies as memory to store data. SSD is also known as a solid-state disk although SSDs do not have physical disks. There are no moving mechanical components in SSD. This makes them different from conventional electromechanical drives such as Hard Disk Drives (HDDs) or floppy disks, which contain movable read/write heads and spinning disks. SSDs are typically more resistant to physical shock, run silently, and have quicker access time, and lower latency compared to electromechanical devices.
It is a type of non-volatile memory that retains data even when power is lost. SSDs may be constructed from random-access memory (RAM) for applications requiring fast access but not necessarily data persistence after power loss. Batteries can be employed as integrated power sources in such devices to retain data for a certain amount of time after external power is lost.
Introduction to Solid-State Drive (SSD)
SSD is a non-volatile storage device, which stands for Solid State Drive, and protocols such as SATA and SAS of traditional hard disk drives (HDD) may be used. New form factors such as the M.2 form factor, and new I/O protocols such as NVM Express have been developed to address specific requirements of the Flash memory technology used in SSDs.
