The Z440 MT has an SSD storage medium which is faster than most medium processor core computers that have been around for more than a year. Most medium processor core 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.
This personal computer's storage speed (SSD) is actually the best storage speed across all medium processor core computers that were released around the same time as the Z440 MT.
The worst storage speed across comparable types of personal computer is HDD.
Computers with a faster storage speed that might be worth looking at include the Zotac ZBOX PI320 (Flash), or the Asus CHROMEBIT (£99.97) (Flash) which also has a higher rating.
