The storage speed of this PC is SSD, which is the most frequently found storage medium on computers that have been on the market for a comparable time to 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.
There are a number of other SSD computers currently available that you might also want to look at including the HP 640 MT, or the Lenovo P900 (£2,016.80) which is cheaper.
Desktop computers with a faster storage speed that might be worth looking at include the Apple Mac Pro (£2,046.55) (Flash) which is also cheaper.
