In Duplicator Mode, it creates an exact 1-to-1 sector clone from one hard drive to another, including partition & boot sector information & all data, at a rate of ~72MB/second, ensuring data integrity & consistency for sensitive operations (data recovery, etc.). In Dock Mode, it can be connected to your host computer through USB (Universal Serial Bus) 3.0, supporting up to 5 Gbps of bandwidth from both hard drives to your computer system. Large capacity drives (tested with up to 4TB 3.5" & 1TB 2.5" drives per bay) can be used to greatly enhance your computers storage/backup capabilities. The value of this hard drive docking station can be further extended through a SATA to IDE hard drive adapter (SAT2IDEADP), which enables you to use any 2.5 or 3.5in IDE hard drive in a SATA hard drive dock slot.
