Tag: solid state drive

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 with electromechanical disks, SSDs are typically less susceptible to physical shock, are usually silent, and have lower access time and latency. However, while the price of SSDs have continued to decline in 2012, SSDs are still about 20 times more expensive per unit of storage when compared to HDDs.
SSDs share the I/O interface technology developed for hard disk drives, thus permitting simple replacement for most…
