Review on 💻 Unitek USB 3.0 to SATA Dual Bay External Hard Drive Docking Station - 2.5/3.5-inch HDD SSD Support, Offline Clone, UASP, 16TB Capacity, 12V/3A Power Adapter by Jennifer Stevenson

I bought this with a new 2TB hard drive to expand my 1TB laptop storage. I used the offline cloning feature to "copy" my almost full (880GB I think) to a new drive. It took over 6 hours, almost 7 hours from start to finish, so don't expect this to duplicate the discs quickly. Also a note on this: when cloning the drive to a larger capacity drive, it turned out that after finishing and installing a new 2TB drive, it only had about 1TB of space. This is because the offline cloning feature automatically creates a partition with the same space as the original drive. Fixing this problem on Windows (Windows 10 in my case) was very easy. Just search "Disk Management" in the search bar so you can see all your drives and their partitions. Then right click on the partition of the new hard drive with data on it (it will be marked as containing data, the other will be marked as empty or unallocated partition) and select "Extend Volume/Storage". Yes then I can select an unallocated partition and it will be merged into one piece so you should now be able to access all 2TB, for reasons it's actually more like 1.85TB. This is long but I hope this helps someone if this happens to you. TL; DR does what it says, takes a long time depending on the size cloned, note that increasing the size can result in more dipping with less disk space and how to fix this yourself.
