A solid-state drive (SSD) is simply a data storage device that uses integrated circuits to store persistent data. This solid state storage is a contrast to the electro-magnetic media (such as traditional platter-based hard drives and floppy disks) that dominated the data storage market for the later part of the 20th century.
While solid-state technology has existed since the 1950s in various forms, it wasn’t until the 1990s that it began to appear in the consumer market. Flash drives, the ubiquitous little USB-based drives used for portable data storage, are an early example of a compact solid-state drive widely adopted by consumers. Astronomical pricing kept computer hard drives based on solid-state technology out of consumer reach until a few short years ago. Now it’s possible to enjoy the benefits of a solid-state drive–such as lightning fast seek times and silent operation–without taking out a loan to do so.
