The Backup Plus drive is sold in the compact packaging shown below. The below left image shows the front of the box which merely tells you there is a portable hard drive with a 1TB capacity insde (in English and in French). The back of the box goes in to a bit more detail on the backup options, as well as on the connector options. In the box you will receive a USB 3.0 connector (which is backwards compatible to USB 2.0), and you can purchase Thunderbolt and Firewire 800 connectors separately.
Inside the box you will find a clear plastic case which houses the drive and the USB 3.0 cable, while a quick start guide is found underneath this case. All software is pre-installed on the drive, so no extra disks are required.
The drive is quite compact, but not the smallest portable drive I have used. The GoFlex Slim has been one of my favorite portable drives to use since it was released, as it is slimmer than a pencil, while the marketing materials for the Backup Plus show it as being marginally thicker than this benchmark.
The surface of the drive is sleek, black aluminum with a Seagate logo printed in one corner on the top. A USB 3.0 connector can be found on one end, and if you remove this universal adapter you can see the SATA power and data connectors for the drive inside. Removing this piece is all you need to do in order to swap your USB 3.0 connection for Thunderbolt or Firewire 800.
