Versatile Features The SDOCK2U33RE offers convenient dual-function performance. As a hard drive duplicator, the SDOCK2U33RE lets you create an exact sector-by-sector clone from one hard drive to another, including partitions and boot sector information, ensuring data integrity and consistency for sensitive operations, such as data recovery. As an external hard drive dock the SDOCK2U33RE lets you connect your drives through either eSATA or USB, with each drive slot individually supporting high capacity 2.5/3.5in hard drives or solid state drives, tested up to 4 TB. Fast Performance With support for SATA III (6 Gbps) you can maximize efficiency with duplication speeds up to 22 GB per minute, and eSATA docking speeds up to 6 Gbps. The Dock can also be connected through USB 3.0 with UASP for transfer speeds up 5 Gbps (70% faster than conventional USB 3.0). See our UASP testing results below for further details. Hassle-free Operation With push button operation and plug-and play installation, the duplicator dock has been specially designed for hassle-free operation. The SDOCK2U33RE lets you quickly dock your hard drives or start duplicating hard drives with the push of a button. Plus, the built-in LED progress bar saves you time by letting you easily monitor the entire duplication process, so you'll know exactly when it's time to start your next operation. Improved Performance with UASP UASP is supported in Windows 8, Mac OSX (10.8 or above), and Linux. In testing, UASP performs with a 70% faster read speed and 40% faster write speed over traditional USB 3.0 at peak performance.
