The Chromebox has a faster storage speed than most new comparable spec computers. This personal computer has an SSD storage medium, whereas most recently released few processor core personal computers have an HDD storage medium. Solid State Drives (SSD) store information in transistors on a circuit board rather than on optical or magnetic media. This has the advantage of being much faster than a traditional HDD drive.
