The Asus E210 has an SSD storage medium which is faster than the HDD storage medium found on most few processor core PCs that were launched around the same time as it. 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 PCs that have been on the market for a similar time to the E210.
Amongst comparable types of personal computer the worst storage speed is HDD.
If the storage speed of this desktop computer is not fast enough for you then you might want to look at the Apple Mac Mini Late 2014 (£650.78) (Flash).
