The ZBOX BI322 has an SSD storage medium which is faster than most few processor core PCs that are a similar age to it. Most newly released comparable spec desktop computers 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 few processor core PCs that were released around the same time as the ZBOX BI322.
Across similar types of personal computer the worst storage speed is HDD.
PCs with a faster storage speed that might also be worth looking at include the Acer M1-601 (£99.99) (Flash).
