The Slot-In PC has a faster storage speed than most few processor core computers that came out around the same time as it. This personal computer has an SSD storage medium, whereas most desktop computers 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.
An SSD storage medium is in fact the best storage speed amongst all similar spec computers that have been around for more than two years.
An HDD storage medium is the worst storage speed amongst comparable types of PC.
