Addonics Mini HDD Duplicator ($45)

Addonics Technologies, Inc. announced the Mini HDD Duplicator Station, a compact storage device that is about the size of a desktop computer power supply.

 
The storage device 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 is a convenient tool for transferring data between different types of hard drives and flash memory cards as well as for cloning hard drives or making back up hard drives. It operates silently without the need for a cooling fan.
 
When used as a duplicator, you insert the master hard drive into the source slot and the destination drive into the target slot. You then 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 source drive slots are designed to accommodate standard 3.5" or 2.5" SATA hard drives, SSDs, or the Addonics family of 2.5" flash drives.
 
If used as a USB 3.0 docking station, the two drives in the source and source drive slots can be connected to any computer via the USB 3.0 or the USB 2.0 port.
 
The drives will appear as two individual drives to the computer. Each drive can be removed and a new drive can be added to the drive slot without the need to restart the computer, similar to using a VHS cassette. There is also a Backup button that works with the bundled backup software to make a copy of data onto one of the two hard drives installed in this docking station.
 
MSRP of the Mini HDD Duplicator Station is $45.
