Closer Look:

As we planned on testing this drive to the maximum, we figured we'd better take a look inside before we jump into testing - in case it doesn't survive. I was a bit confused at first as the drive is clearly labeled as a Samsung "Spinpoint", but lower down on the drive it states "Momentus" (Seagate property). I then realized that a while back Seagate bought the mechanical drive division from Samsung and this is now their love-child.

The drive is wrapped and padded from all sides by the silicon bumper and there is even a bit of a pad on the top lid of the drive to prevent anything from bumping on that side and damaging the drive where the silicon bumper doesn’t cover. It’s a good idea and we’ll see if it holds up a little later on.

Stripped Bare

Silicon Power has used a small interface card to convert the SATA 3 6Gbps connector on the drive to a speedy USB 3.0 port that is capable of 5Gbps. Thankfully, mechanical drives don't run anywhere near this throughput so we shouldn't be seeing any bottleneck on this drive by the controller and interface.

On the next page we'll cover some of our testing ideas before we jump right into testing the performance of this drive.
