The Lenovo Chromebox has an SSD storage medium which is faster than the HDD storage medium found on most few processor core computers that were released in the last year. 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.
An SSD storage medium is in fact the best storage speed amongst all few processor core computers that were released in the last 12 months.
An HDD storage medium is the worst storage speed across comparable types of computer.
