To get it out, you need to pry the box open, disconnect the controller and there you have the hard drive. Interestingly, after “sourcing” the drive you are still left with a controller, a case, a USB 3.0 Cable, and a power adapter. You have to admit. This is not a bad deal for minus forty dollars. (And minus a warranty) This, of course, raised a few questions marks with us, so we asked around. If my understanding of the explanation is correct, it may come from one of two reasons: The first option is the drives inside the Expansion unit are older, refurbished, or simply visually impaired drives. The other explanation we got was from the supply and demand realm. The OEM drive is targeting PROs who are willing to pay more, where the expansion unit is aimed at the general market, who are more price sensitive. I guess Seagate are also not committed to supplying the same internal hard drive in all their expansion units, so we have just been lucky. Either way, there is a very high chance, I would say around 100%, that pulling this trick off, will void your Seagate Expansion warranty.
