Let’s find out what this little device can do and whether or not it’ll be a worthy addition to your PC peripherals.

A Closer Look – Cloning

Having a closer look at the main unit, we can see the source and target SATA connectors, along with the IDE source connection on the left. The EZ-Clone also supports connecting 2.5″ IDE drives by using the enclosed adapter board. The blue button in the middle will start the cloning process when pressed. The row of LED lights indicates when drives are connected and the progress of the cloning operation. The two outer lights illuminate red, and the four center lights illuminate blue. On the back, you’ll find the on/off switch, the AC adapter’s power connection, USB cable connector, and the auxiliary power connector for the included 4-pin Molex cable.

The cloning process is a snap to complete and works great. Above, I cloned a 160 GB SATA HDD to a 1 TB SATA HDD, which took about 40 minutes to complete. The extra capacity on the 1 TB drive shows as an unallocated partition, but using Windows disk management allows you to quickly extend the partition and use all the available capacity. Quick and painless cloning at a touch of a button, nice!

Closer Look – HDD to USB 3.0 Adapter

The Kingwin EZ-Clone can also be used as a HDD to USB 3.0 adapter, and two drives can be accessed simultaneously. NOTE: You cannot connect to the IDE Source and SATA1 Source at the same time. Only the IDE drive will be detected if both source drives are attached at the same time. Connect the SATA drive to the SATA2 Target interface to access IDE and SATA drives at the same time. Otherwise, you can hook two SATA drives to the SATA1 Source and SATA2 Target ports to access two SATA drives at the same time.

I hooked up a couple of 3.5″ SATA HDDs to the EZ-Clone and connected the unit to a computer’s USB 3.0 port. Both drives were recognized quickly and showed up in the “Computer” window. Transferring files between the two HDDs connected to the unit worked great, and file transfers to either drive from any other location worked as expected too.

For a quick test, I ran ATTO Disk Benchmark to check performance. The first run of ATTO was on the WD Green drive shown in the picture above. The second run of ATTO was performed on a Samsung 840 Pro SSD. Obviously, the performance numbers were much better using the SSD.

The Kingwin EZ-Clone is a nifty device that works as intended and has a lot of versatility. The cloning feature works terrific and is about as easy as cloning drives can possibly get. The less tech savvy person, who may be intimidated by cloning software, will appreciate this device for sure. While it is true the cloning process takes longer than what can be done with a PC and its accompanying cloning software, the advantages here are that no PC is required and the ease in connecting drives to this unit rather than having to install them in a PC. It’s as simple as connecting two drives, hitting the blue button, and go!

When used as a SSD/HDD to USB 3.0 adapter, the ease of use remains intact. No drivers are required; and in our case, the connected HDDs were immediately recognized and available for use. Again, simple and straightforward.

As far as pricing goes, the unit is available at various eTailers for around $39.95. Considering everything the EZ-Clone can do, I think that’s a heck of a bargain. A device like this can be a valuable tool in anyone’s PC arsenal, especially when HDD swaps are required or additional storage drives are needed. Ease of use, price point, and great versatility all add up to to the Kingwin Ez-Clone being Overclockers approved!

:( Sort of obsolete already. I suppose this may relate to the issue of GPT vs. MBR partition tables. If the device was a little smarter it could work around this but the more changes it makes in the clone operation (as opposed to a byte by byte copy) the more opportunity there is for something to go wrong.

Thanks for the review!
