Barracuda Green SATA Product Manual, Rev. D 9
1.0 Introduction
This manual describes the functional, mechanical and interface specifications for the following Seagate
®
Barracuda
®
Green SATA model drives:
These drives provide the following key features:
• 5900 RPM spindle speed
• Seagate
®
SmartAlign™ technology manages read-modify-write conditions dynamically in the drive without
host computer intervention, allowing a 4K drive to behave like a legacy 512-byte sector drive without the
necessity of a hardware utility.
• High instantaneous (burst) data-transfer rates (up to 600MB per second)
• Perpendicular recording, Tunneling Magnetoresistive (TMR) recording heads and EPRML technology, for
increased areal density
• State-of-the-art cache and on-the-fly error-correction algorithms
• Native Command Queueing with command ordering to increase performance in demanding applications
• Full-track multiple-sector transfer capability without local processor intervention
• Quiet operation
• Compliant with RoHS requirements in China and Europe
• SeaTools diagnostic software performs a drive self-test that eliminates unnecessary drive returns.
• Support for S.M.A.R.T. drive monitoring and reporting
• Supports latching SATA cables and connectors
• Worldwide Name (WWN) capability uniquely identifies the drive.
1.1 About the Serial ATA Interface
The Serial ATA interface provides several advantages over the traditional (parallel) ATA interface. The primary
advantages include:
• Easy installation and configuration with true plug-and-play connectivity. It is not necessary to set any jumpers
or other configuration options.
• Thinner and more flexible cabling for improved enclosure airflow and ease of installation.
• Scalability to higher performance levels.
In addition, Serial ATA makes the transition from parallel ATA easy by providing legacy software support. Serial
ATA was designed to allow you to install a Serial ATA host adapter and Serial ATA disk drive in your current system
and expect all of your existing applications to work as normal.
