The HP 440 has a faster storage speed than most medium processor core personal computers that are a comparable age to it. This desktop computer has an SSD storage medium, whereas most medium processor core personal 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 actually the best storage speed across all medium processor core personal computers that have been available for a comparable time to the 440.
The worst storage speed across comparable types of desktop computer is HDD.
