The CELSIUS M740 has a faster storage speed than most medium processor core personal computers that are a similar age to it. This computer has an SSD storage medium, whereas most medium processor core personal computers that came out 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 across all medium processor core personal computers that have been on the market for more than a year.
An HDD storage medium is the worst storage speed across similar types of PC.
