Integrated, and assembled in the United States to satisfy the requirements of demanding audio and video professionals, the Rocpro line can support a Solid State Drive "SSD" or a fast SATA high-capacity 3.5" hard drive, and has a unique stylish and ruggedized design that will complement any desktop. It features a recycled aluminum case that can be conveniently stacked or mounted vertically. With its built-in power supply and fan-less and quiet operation, the Rocpro can be easily moved from one desktop environment to another using the provided carrying case. The Rocpro is compatible with both Windows and Macintosh environments without any software installations. The Rocpro external hard drives deliver extraordinary performance, rapid file transfer speeds (up to 5,000 Mbits/s via USB 3.0, up to 800 Mbits/s via FireWire 800 or up to 3,000 Mbits/s via eSATA), and proven reliability for both Mac and PC users. And because it provides up to 3TB single hard drive; one of the first of its kind, this device is one of the most, if not the most, versatile desktop and/or portable external drives in the world. The built-in power supply offers the user added convenience by eliminating the need to carry nonstandard and sometimes hefty adaptors and cables that are normally required to power typical hard drives. The power supply contained in the Rocpro line is Auto-Switchable 240VA/100VA (will work internationally) and uses any standard computer cable, no matter what country you are in.
