Nearly perfect! 55

The docking station is really fast, provided one considers 2 things:
1. It has a USB 3.0 port on the terminal with a good controller
2. The hard drives are plugged to date as possible and have good properties (SATA III (6Gb / s) recommended!)

================================================== ===

External Data Storage:

I run the station on my Macbook Pro 15 "Mid 2014 (current model) (easily installed automatically by the operating system) attached with USB 3.0 interface and have 2 screenshots below. Information on the respective disks can be read in the screenshot!
One shows the same hard drive (Seagate Momentus 2.5 ") (via USB 3.0 connected to the Macbook) in the comparison between the standard included USB 2.0 cable and the Dock.
The other shows the comparison between two different WD drives, an older and a newer, both of which are connected in the dock via USB 3.0.

I have the station already operated on a Windows PC (installation problems automatically by the operating system) and the data rates are very similar.

Overall, I am very excited by the dock as an external data storage, since, as can be seen from the new WD drive, really is very fast and also the maximum out rausholt from an older drive.

================================================== ===

Clone function:

Have cloned a bit in the tooths laptop on a 250 GB SSD, a 160GB HDD. After that went directly in BIOS's and AHCI turned on (was made), and subsequently launched Windows 7 64 bit immediately properly. Then even the latest Intel Storage driver is installed and the operating system with the manufacturers of SSD software optimized for SSD operation and now everything is perfect! Read Before with the old HDD 30 MB / s and write, now with the SSD 230 MB / s (SATA II because of the older laptops), so everything tip top and very fast!

Again, I was fully convinced the station. Cloning also works flawlessly and walks briskly across the stage!

================================================== ===

The only negative:

The docking station can not be operated under Windows 7 on Mac when Windows in a virtual machine (VMware Fusion) runs. Boot Camp I have not tried.
It would be nice if a Windows 7 driver can be supplied, which enables the use of the Mac.
