The HP 440 MT has an SSD storage medium which is faster than most medium processor core personal computers that have been on the market for the last year. Most comparable spec personal computers that were launched around the same time as 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 amongst all recently released medium processor core personal computers.
Amongst similar types of computer the worst storage speed is HDD.
