Rocstor 3TB Rocpro 900e External Hard Drive

The ROCPRO 900E 3TB USB3.0 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 4TB 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 Rocpro 900e is made with aluminum aloy, making this enclosure both ruggedized and durable. An exclusive shock-absorbing mechanism is built into the enclosure. Its function is to keep the hard drive secure within the casing, while dissipating the heat produced by the hard drive.

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. In addition, due to the heat dissipating automatically through the enclosure, there is no fan installed, which makes the device virtually silent while it is operating, which makes the device virtually silent while it is operating.
