We've put it to the test, and the XtremKey USB 3.0 is LaCie's strongest, toughest USB key yet. Its ZAMAC metal alloy construction withstands severe shock, relentless pressure, dizzying drops, and temperatures as bone chilling as -30°C (-22°F) and as scorching as 200°C (392°F). It features heat, cold, drop, shock, and pressure resistance to protect your data from the outside elements, plus AES 256-bit software encryption** to secure it from the inside.

Extremely large files need extreme speed. With the LaCie XtremKey's USB 3.0 interface, you get speeds of up to 230 MB/s for extraordinarily fast file transfers that allow you to transfer three HD movies or 9,200 photos in less than one minute***. USB 3.0 represents an enormous speed increase from USB 2.0, and best of all, it's backward compatible with USB 2.0. Never worry about connectivity.
