On first look, the Seagate Expansion drive is very plain. The enclosure is completely made lightly textured black plastic, and the only visible marking on the drive is the Seagate logo on the front. Maybe the rounded off and slightly sloped front end are Seagate's attempt to make this basic USB 3.0 drive look fast.
The side profile shape of the Seagate Expansion drive is of a windswept looking parallelogram.
The drive was designed to lie flat on one side, and is not meant to stand up. The bottom has rubber feet, vents and a product information sticker. Having all of this at the bottom helps maintain a simple sleek look during regular operation of the drive. As the vents are on the bottom, it's best to use the drive when it's on a hard surface, and not on something like carpet, which would block the ventilation.
The back of the Seagate Expansion has the DC power and USB 3.0 micro-B receptacles.
The Seagate Expansion includes an AC-to-DC power brick and a USB 3.0 micro-B to standard-A cable.
