Packaging and accessories

The US70 1TB is packaged in a cardboard box. The front side features a clear plastic window which showcases the SSD. In addition, the complete product name of the SSD is printed on the upper left side while the storage capacity and warranty are on the lower side.

 

The back side of the box offers additional information about the product and the manufacturer.

 

The SSD has decent protection inside the packaging. While the cardboard of the packaging is thin, the SSD itself is placed inside a clamshell tray.
