Introduction
A solid-state drive (SSD, sometimes improperly referred to as a "solid-state disk", or "electronic disk") is a data storage device that uses integrated circuit assemblies as memory to store data persistently. SSD technology uses electronic interfaces compatible with traditional block input/output (I/O) hard disk drives. SSDs do not employ any moving mechanical components, which distinguishes them from traditional magnetic disks, such as hard disk drives (HDDs), or floppy disks, which are electromechanical devices containing spinning disks and movable read/write heads. Compared to electromechanical disks, SSDs are typically less susceptible to physical shock, are silent, and have lower access time and latency, but are relatively more expensive per unit of storage. The prices have continued to decline since 2012.

In general, SSDs share the I/O interface technology developed for hard disk drives, thus permitting simple replacement for most applications. New technology that is designed specifically for SSDs, NVME, has also become common in recent years. They make use of PCI-e to deliver even higher performance and throughputs.

Most SSDs use NAND-based flash memory, which retains data without power. For applications requiring fast access, but not necessarily data persistence after power loss, SSDs may be constructed from random-access memory (RAM). Such devices may employ separate power sources, such as batteries, to maintain data after power loss. Between the two, 3D XPoint is a viable potential technology.

Hybrid drives combine the features of SSDs and HDDs in the same unit, containing a large hard disk drive and an SSD cache to improve performance of frequently accessed data. These devices may offer near-SSD performance for many applications.
