Discontinued and replaced by HDUSI325-B
This Addonics Mini HDD Duplicator Station is a feature rich storage device. It is designed to be used as a simple 1:1 HDD/SSD duplicator or as a fast USB 3.0 docking device for up to two SATA hard drives. It comes in a very small foot print, about the size of a Desktop computer power supply, and operates silently without any cooling fan.
As a 1:1 HDD/SSD duplicator, simply insert the master hard drive into the SOURCE slot and the destination drive to the TARGET slot, press the CLONE button and the duplication process starts automatically. All the content, including boot sector and partition table, on the master drive will be copied onto the destination drive sector by sector. The SOURCE and the TARGET drive slots are designed to accomodate standard 3.5" or 2.5" SATA hard drive or Addonics family of 2.5" Flash drive. There is no special tool required to install the drive.
As a fast USB 3.0 docking station, the two drives in the SOURCE and TARGET drive slots can be connected to any computer via the SuperSpeed USB 3.0 port or the High Speed USB 2.0 port. The drives will appear as two individual drives to the computer. Each drive can be removed and new drive can be added to the drive slot without the need to restart the computer, similar to using the VHS cassette. There is also a BACKUP button that works in unison with the bundled backup software to conveniently make a copy of all your important data onto one of the two hard drives installed in this docking station.

Note:
1.The speed here is for reference only. The speed were measured basing on using 3.5" SATA III 320 GB hard drive for both source and target. The transfer rate varies depending on the speed of the source and destination drive.
2. In order to install drive size over 2TB, the OS must support GPT drive partition in standard 512 bytes sector. All modern OS such as Windows 7 and later, Mac OS X or the latest LInux Kernel support GPT drive partition and should use the standard model HDMU3
For older Windows XP system that does not support GPT drive partition, the hard drive over 2TB must be partitioned in MBR with 4K sector. In this case, you will need to use the model HDMU3-X. However older Linux and Mac OS do not support drive with 4K partition. So this will limit the drive to be used in the Windows XP system only. Drive partitioned in 4K sector will not work with any Addonics NAS adapters or other device that use the embedded Linux OS.
