The Intel Core i5 Delta has an SSD storage medium which is faster than most desktop computers of this type and age. Most similar spec desktop computers that were released one year ago 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 in fact the best storage speed amongst all comparable spec personal computers that were launched around the same time as the Intel Core i5 Delta.
The worst storage speed amongst similar types of PC is HDD.
Other SSD PCs currently available which you might also want to consider include cheaper personal computers such as the Fujitsu D556 (£459.78), or the HP 800 G2 (£877.43).
