Odyssey 120GB Dock & Cart Removable HD Storage Syst Expandable: Docking system is forward compatible with next-generation hard disk cartridges as they enter the market, offering expandable performance. Speed and Convenience: With the added benefit of removability, the Odyssey system minimizes the time needed for backup and restore operations while drag-and-drop file access makes moving data as easy as the click of a mouse. Shock Protection: Odyssey hard disk cartridges are built to withstand a 900 G-force shock, the equivalent of being dropped from one meter onto a concrete surface. Soft-load Mechanism: A unique, soft-load and eject mechanism not only allows cartridges to be loaded with one finger, but also protects against accidental ejection during data transfer.
