The Seagate Cheetah 15K.7
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 desktop 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.
If you read my hard drive reviews often then you'll most likely wonder why I show the sides of the drives; today is a good example. Here we see some additional threaded holes that are not part of the standard mount, three screw form factor standard.
The other side is a mirror image of the first.
The back side of the drive has all of the standard SAS power and data connectors where they should be.
Here we see the difference between SAS (top) and SATA (bottom) power and data connectors. SAS has an additional set of data pins at the top of the connector. Also, you can't cut a SATA power and data wires to work with SAS drives; been there, tried that.
