The DELL Chromebox 3010 has an SSD storage medium which is faster than most few processor core PCs that are a comparable age to it. Most few processor core PCs that have been around for a comparable time 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.
This desktop computer's storage speed (SSD) is in fact the best storage speed amongst all few processor core PCs that have been on the market for more than a year.
An HDD storage medium is the worst storage speed amongst similar types of desktop computer.
Computers with a faster storage speed that might also be worth considering include the Apple Mac Mini Late 2014 (£650.78) (Flash).
