The low initial acquisition cost of the Formac ProOpt makes it particularly attractive for new users of MO technology. It offers MO's typical features, like highest data safety and low price per MB in a compact 3.5" disk format. This makes it particularly suited to the backing up and archiving of large amounts of sensitive data. Due to its small size, it is also ideal for data transport and exchange. Like almost all removable drives from Formac, it is housed in a solid metal case which can be stacked, thus allowing a modular expansion of the whole system.
