Crucial SSDShort for Solid-State Drive (or Solid-State Disk, although it doesn't use a disk mechanism), SSD is a drive that uses non-volatile memory as a means of storing and accessing data, much like computer RAM. Unlike a hard drive, an SSD has no moving parts, which gives it advantages such as accessing stored information faster, noiseless operation, higher reliability, and lower power consumption. The picture shows an example of an SSD made by Crucial.

As the costs have come down, SSDs have become suitable replacements for a standard hard drive in both desktop and laptop computers. SSDs are also a great solution for netbooks, nettops, and other applications that don't require a lot of storage.

Tip: Although an SSD uses flash memory, it should not be confused with a USB jump drive or Adobe Flash.

History of the SSD

The first SSD was implemented in IBM supercomputers in the 1970s and 1980s. They have since been drastically improved upon and offer storage capacities of over 2 TB for home computers.
