Archgon unity I MH-3507-U3A is the first flat type of hard drive docking station in the world. Compared to traditional vertical type docking station, the benefit of flat/horizontal type design is in order to alleviate the impact of vibration on drive's SATA connector. In addition, users could eject the drive without any damages to hard drive connector by using Archgon patented drive ejection button. Both these two ways could extend the lifetime of hard drive efficiently. Innovative stackable design allows heavy users to save space as well.
