The storage speed of this desktop computer is Flash, which is the most commonly found storage medium on personal computers of this age and type. Flash Drives 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.
We think you might also be interested in some of the alternative Flash desktop computers currently available including because of it's better review score, the Apple Mac Pro Late 2013 (£3,750.00).
