Designed with a military theme in mind, the Ammo features many things that set it apart from ordinary 2.5' enclosures. Made of military grade metal, the Ammo is designed to withstand harsh conditions. Along with its data access RFID security feature, the physical protection of the drive was thought of as well. Within the enclosure is a silicon absorbing unit that reduces vibration and physical damage to the drive. Paired with the military grade casing and RFID security feature, In Win's Ammo is much more than a standard drive enclosure.
