The DMP Electronics EBOX-3350MX-AP has a Flash storage media which is faster than the HDD storage media found on most desktop computers of a similar type and age to it. 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. Similar spec computers that are a comparable age to the EBOX-3350MX-AP storage medias range from HDD to SSD.
If the storage speed of this desktop computer is too slow for you then you might want to look at the DELL Chromebox 3010 (£185.99) (SSD).
