LaCie and Porsche Design worked together to combine speed, design, and technology to create a USB key that is as beautiful as it is functional. The LaCie Porsche Design USB Key is constructed with solid steel, meaning the compact design doesn't sacrifice strength. Slim size, steel strength. The LaCie Porsche Design Key's USB 3.0 interface delivers speeds up to 95MB/s. That means much faster file transfers compared with USB 2.0 keys. And best of all, since USB 3.0 is backwards compatible with USB 2.0, there's never any worry about connectivity.
