The Seagate Barracuda XT
Our drive was so new that it arrived in a less than OEM style box, it wasn't even wrapped in an antistatic bag but we aren't complaining about getting a drive right from the factory. Like nearly all of Seagate's hard drives the label on the front shows the model name and serial number.
On the outside there isn't really much to see. On the back side of the drive all of the electronics are on the opposite side of the board.
The side of the drive has all of the standard mounting locations for a 3.5 inch form factor drive.
The power and data ports are where they should be located. There are a couple of jumpers on the back as well for special configurations.
