The SATDOCK22RE USB and eSATA Standalone Duplicator Dock lets you duplicate/clone an existing hard drive without the use of a host computer system or can be connected to a computer system for use as an external hard drive dock.As a hard drive duplicator you can create an exact 1 to 1 sector clone from one hard drive to another including partition and boot sector information and all data at a rate of 72MB/second - ensuring data integrity and consistency for sensitive operations such as data recovery.As an external hard drive dock the duplicator/dock supports plug-and-play installation and can be connected to your host computer through USB 2.0 or eSATA providing data transfer speeds up to 480Mbps or 3Gbps respectively from the hard drives to your computer system.Not having to install the hard drives into an enclosure or tray system allows for quick setups - a perfect solution for situations that require swapping through multiple drives which combined with no driver or software installation requirements delivers a convenient and versatile storage solution. The value of this hard drive docking station can be extended using a SATA to IDE hard drive Adaptor (SAT2IDEADP) which enables you to use any 2.5 or 3.5in IDE hard drive in a SATA hard drive dock slot.
