This package contains one TR-1 Mini Data Cartridge for use with Travan technology drives. It features a storage capacity of 400MB in native mode and 800MB with data compression. By combining high capacity with high speed, Travan technology brings you a true multi-functional storage solution. Travan offers a data transfer rate of 500KB per second, and enough capacity so you can store the entire contents of your hard drive on a single minicartridge. And because Travan technology drives can read QIC minicartridges, your existing backup library is still useful.
