A Closer Look
Figure 3 shows the rear side of the drive, where you can see the USB 3.0 port and a white LED. The case of the product is made of white plastic, while the top is a plate of red brushed aluminum.
A very interesting feature of the Seagate Backup Plus is the changeable interface. Just pull the rear of the case and the interface disconnects from the actual hard disk drive, as shown in Figure 4. You can replace the USB 3.0 interface by a Thunderbolt or FireWire interface, sold separately.
This feature can also be interesting for other purposes. For example, you can connect the interface to a common 2.5” hard disk drive (laptop HDD) in order to access the drive through the USB 3.0 interface.
The presence of a common SATA connector was a clue that there was a common internal hard disk drive inside the Backup Plus. We opened the case and found a Seagate Momentus 2.5” drive (Model ST1000LM024, 5,400 rpm, SATA-300, 16 MB buffer). Figure 5 shows the drive.
