The Revo One RL85 has an SSD storage medium which is faster than most few processor core PCs that were released more than a year ago. Most comparable spec desktop computers that are a similar age to it 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.
An SSD storage medium is in fact the best storage speed across all personal computers that have been around for a comparable time to the Revo One RL85.
Across similar types of personal computer the worst storage speed is HDD.
