A solid-state drive (SSD) is a type of solid-state storage device that uses integrated circuits to store data persistently. It is sometimes called semiconductor storage device , solid-state device , or solid-state disk .
Formerly, but this company has exited the storage business. No No Intel [13] United States No Sold its NAND flash memory and SSD businesses to SK Hynix. Intel has terminated its Optane line of memory. Sold its NAND flash memory and SSD businesses to SK Hynix. Intel has terminated its Optane line of SSDs. No
A solid-state drive (SSD) provides secondary storage for relatively complex systems including personal computers, embedded systems, portable devices, large servers and network-attached storage (NAS). To satisfy such a wide range of uses, SSDs are produced with various features, capacities, interfaces and physical sizes and layouts.
Today storage devices may be internal or external to a computer system. In the 1950s, introduction of magnetic tapes and hard disk drives allowed for mass external storage of information, which played the key part of the computer revolution. [6] Initially all external storage, tape and hard disk drives are today available as both internal and ...
Non-volatile memory (NVM) or non-volatile storage is a type of computer memory that can retain stored information even after power is removed. In contrast, volatile memory needs constant power in order to retain data.
Historically, memory has, depending on technology, been called central memory, core memory, core storage, drum, main memory, real storage, or internal memory. Meanwhile, slower persistent storage devices have been referred to as secondary storage, external memory, or auxiliary/peripheral storage.
In computer storage, a disk buffer (often ambiguously called a disk cache or a cache buffer) is the embedded memory in a hard disk drive (HDD) or solid-state drive (SSD) acting as a buffer between the rest of the computer and the physical hard disk platter or flash memory that is used for storage.

For the sake of simplicity, only the details of one SSD are demonstrated. Modern SSDs usually contain 16 or more flash memory channels which can be utilized concurrently for flash memory array I/O operations. Considering 512 MB/s bandwidth per channel, the internal bandwidth of an SSD with 16 flash memory channels is about 8 GB/s.
