Intel Solid-State Drive E5400s Series - solid state drive - 80 GB - SATA 6Gb/s

There are no moving parts to solid state drives (SSDs). By contrast, hard disk drives (HDD) use a mechanical arm to move around and read information from a spinning platter. In addition, SSDs use non-volatile memory which simply means that when the memory is turned off it won’t “forget” what was stored.

So, if you want storage that leads the pack for performance, stability, and efficiency, a solid state drive (SSD) should be your pick.
