Rated 5 out of 5 by from Best Hard Drive Docking Station I have usedThis is a great product! The ability to clone drive to drive is very handy when you ran out of sata connectors on a motherboard and looking to clone a drive. I have had a Thermaltake and Roswill Hard drive docks and both broke in less then a year. The only thing I would do to make the product better would be make the body of it out of metal not plastic.

Rated 5 out of 5 by from Won't Work with NAS DrivesNot impressed at all. I have a Synology NAS DS713+ with a single drive. Wanted to use this to clone, and because software I was using (dbpoweramp) would not convert music files with it in the NAS. This seemed like the perfect fit. However, it won't work because the docking station does not see the drive as the drive has no Drive Letter. Support advised me to assign a drive letter that would have formatted the drive erasing all my data!!! Fortunately, my limited computer skills at least knew not to do that. They weren't of much help. Sending it back.UPDATE 5/25/16-Received another email from support. They pretty much admit that this won't work with NAS drives.

Rated 5 out of 5 by from Excellant product. Makes it pretty easy to clone a disc.Pretty easy to use. Highly recommend this. New disc has to be larger or equal in size to old one.

Rated 5 out of 5 by from Works very well!I bought this dock in December of 2014 and have had no issues with it. The cloning software works great and the dock even has lights that show you the cloning progress. The USB 3.0 is a huge plus, because you get full speed out of your drives. So far I have only plugged 2.5 inch drives in, but they've all worked. I do wish it had a spacer for the smaller drives, but it doesn't effect the way the device performs. All in all its a great dock that does what it's supposed to do!
