Tourbo HGST 500GB the drive is certainly one of the smallest I have seen it is thick and has a single USB 3.0 connector and a status light.1. As the drive have no button only one USB connector which makes it feel less sturdy.2. The price of the Drive is bit high but it is good as comparison to other drives of 7200 RPM.3. The Drive perfomance is good, faster and smaller in size.Overall it is a portable storage for all digital files.
