Buffalo will present an external HDD casing with a capacity from 160 to 400Gb and a complete security software suit to protect your data (data encryption in AES (256bit) or thorough formatting for example). The casing is also designed in such a way that the heat is evacuated in the best way possible (and thus extending the life cycle of the disc). Buffalo will even offer a fan kit (14dB) that connects straight onto the HDD and provide even a better cooling.
