When referring to drive capacity, one gigabyte, or GB, equals one billion bytes and one terabyte, or TB, equals one trillion bytes. Your
computer’s operating system may use a different standard of measurement and report a lower capacity. In addition, some of the listed
capacity is used for formatting and other functions, and thus will not be available for data storage. Actual quantities will vary based on
various factors, including file size, file format, features and application software. Actual data rates may vary depending on operating
environment and other factors. The export or re-export of hardware or software containing encryption may be regulated by the U.S.
Department of Commerce, Bureau of Industry and Security (for more information, visit www.bis.doc.gov), and controlled for import and

Seagate Kinetic HDD Product Manual, Rev. A 6
1.0 INTRODUCTION
This manual describes the functional, mechanical and interface specifications for the following:
Seagate® Kinetic HDD model drives:
These drives provide the following key features:
•5900 RPM spindle speed.
• High instantaneous (burst) data-transfer rates (up to 60MB per second).
•Perpendicular recording technology provides the drives with increased areal density.
•State-of-the-art cache and on-the-fly error-correction algorithms.
• Simple GetLog command usage to obtain logged data information stored in device.
• Supports Ethernet enabled SAS connectors (Connector pins shown in Table 4.1.1).
• State-free Key-Value Object Store with Remote Procedure Calls (RPC).
•Worldwide Name (WWN) capability uniquely identifies the drive.
• Easy communication via Kinetic Application Programming Interface libraries.
1.1 ABOUT THE ETHERNET INTERFACE
The Ethernet provides advantages over traditional SATA and SAS interfaces. The primary advantages include:
• Connects storage directly into existing data center fabric
• Allows direct TCP/IP communication from any node in the network to the storage device
• Eliminates traditional storage server needs as protocol communication
• Retains the standard SAS hardware interface connector to provide system builder adaptability,
while enabling Ethernet
