Archgon Unity II MH-3507HUB-U3A is the first flat type hard drive docking station including extra 3 ports of USB 3.0 hub. Compared to traditional vertical type docking station, the benefit of flat/horizontal type design is in order to alleviate the impact of vibration on connector. In addition, users could eject the drive without any damages to hard drive's connector by using Archgon patented drive ejection button. Both these two ways extend the lifetime of hard drive efficiently. Innovative stackable design allows heavy users who need more than one docking stations and save space as well. Moreover, 3 port of USB 3.0 hub solve the problem of insufficient USB port from notebook and users can connect other USB devices such as mouse, pen drive, etc.
