The Fujitsu Esprimo E420 has an SSD storage medium which is faster than most personal computers of this age and spec. Most few processor core PCs that were released more than two years ago 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 personal 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 two years.
An HDD storage medium is the worst storage speed amongst comparable types of personal computer.
