The Seagate Savvio 10K.3
The top of the drive is typical Seagate. All of the model and serial information is located on the label on the top of the drive; you can tell just from holding the drive that is sturdier than a standard notebook drive.
A couple of years ago Seagate started mounting all of the components on the other side of the board, so there isn't much to see here.
The sides of the drive have the mounting points in the traditional locations. Here we see a notebook 2.5 inch drive compared to the 10K.3, a 12.5mm drive.
The back side of the drive has all of the standard SAS power and data connectors where they should be. On top is a notebook drive with a SATA interface for reference and to see the difference between the two.
