Taking the external harddrive market to new levels with 640GB capacity! For many people that is huge and would never be filled. Announced in September 2006 and available in the UK now, this USB or Firewire plug-in device looks fantastic.

The main difference over the Minimax version, apart from capacity, is the RAID 0 feature and a built-in Hi-Speed USB (USB 2.0) hub for future expansion.
