The EliteDesk 705 G1 SFF has a faster storage speed than most few processor core PCs that have been on the market for around the same time as it. This computer has an SSD storage medium, whereas most few processor core PCs 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.
This PC's storage speed (SSD) is actually the best storage speed across all few processor core PCs that have been around for more than a year.
The worst storage speed across similar types of PC is HDD.
If the storage speed of this desktop computer is not fast enough for you then you might also want to consider the Apple Mac Mini Late 2014 (£650.78) (Flash).
