The Package
The Seagate 400GB Barracuda 7200.8 SATA hard disk came in a sealed plastic bag which protects it against moisture as well as electrostatic charges.
Inside, the hard disk is further protected against shock and direct force by a semi-rigid plastic box.
Inside the box is the focus of this review - the Seagate 400GB Barracuda 7200.8 SATA hard disk!
We will examine this drive in detail soon enough, but let's go through its specifications first.
