1.0 Introduction This manual describes the functional, mechanical and interface specifications for the following Seagate Momentus® 5400.4 SATA model drives: • ST9250827AS • ST9200827AS • ST9160827AS • ST9120817AS These drives provide the following key features: • 5,400-RPM spindle speed. • 8-Mbyte buffer. • Quiet operation. Fluid Dynamic Bearing (FDB) motor. • High instantaneous (burst) data-transfer rates (up to 150 Mbytes per second).
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 normally 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.
2.0 Drive specifications Unless otherwise noted, all specifications are measured under ambient conditions, at 25°C, and nominal power. For convenience, the phrases the drive and this drive are used throughout this manual to indicate the ST9250827AS, ST9200827AS, ST9160827AS, and ST9120817AS models. 2.1 Specification summary table The specifications listed in this table are for quick reference. For details on specification measurement or definition, see the appropriate section of this manual.

2.7 Seek time Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using drive diagnostics. The specifications in the table below are defined as follows: • Track-to-track seek time is an average of all possible single-track seeks in both directions. • Average seek time is a true statistical random average of at least 5,000 measurements of seeks between random tracks, less overhead.
2.9 Power specifications The drive receives DC power (+5V) through a native SATA power connector. 2.9.1 Power consumption Power requirements for the drives are listed in the table on page 8. Typical power measurements are based on an average of drives tested, under nominal conditions, at 25°C ambient temperature. • Spinup power Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating speed.
2.9.1.1 Typical current profile Figure 1. Typical +5V only startup and operation current profile 2.9.2 Deferred spinup Momentus 5400.4 SATA drives do not support the deferred spinup option. If you require this option, refer to the Momentus 5400.3 SATA Blade Server family of drives. 2.9.3 Conducted noise Input noise ripple is measured at the host system power supply across an equivalent 15-ohm resistive load on the +5 volt line.
2.9.5 Power-management modes The drive provides programmable power management to provide greater energy efficiency. In most systems, you can control power management through the system setup program.
2.10 Environmental specifications 2.10.1 Ambient temperature Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. Actual drive case temperature should not exceed 65°C (149°F) within the operating ambient conditions. Operating: Nonoperating: 2.10.
2.10.5 Shock All shock specifications assume that the drive is mounted securely with the input shock applied at the drive mounting screws. Shock may be applied in the X, Y or Z axis. 2.10.5.1 Operating shock These drives comply with the performance levels specified in this document when subjected to a maximum operating shock of 325 Gs based on half-sine shock pulses of 2 msec. Shocks should not be repeated more than two times per second. 2.10.5.
2.11 Acoustic emission Drive emission of sound is measured consistent with the ECMA-74 and its’ referenced standards. Testing is conducted at room temperature (approximately 25C). Emissino levels are reported as the total A-weighted sound power levels for, steady state, idle and active (seek) modes of operations.

2.15 Environmental protection Seagate designs its products to meet environmental protection requirements worldwide, including regulations restricting certain chemical substances. 2.15.1 European Union Restriction of Hazardous Substances (RoHS) The European Union Restriction of Hazardous Substances (RoHS) Directive restricts the presence of chemical substances, including Lead (Pb), in electronic products effective July 2006.
3.0 Configuring and mounting the drive This section contains the specifications and instructions for configuring and mounting the drive. 3.1 Handling and static-discharge precautions After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic discharge (ESD) hazards.
3.2 Configuring the drive Each drive on the Serial ATA interface connects in a point-to-point configuration with the Serial ATA host adapter. There is no master/slave relationship because each drive is considered a master in a point-to-point relationships. If two drives are attached on one Serial ATA host adapter, the host operating system views the two devices as if they were both “masters” on two separate ports. This means both drives behave as if they are Device 0 (master) devices.
3.4 Drive mounting You can mount the drive using four screws in the side-mounting holes or four screws in the bottom-mounting holes. See Figure 4 for drive mounting dimensions. Follow these important mounting precautions when mounting the drive: • Allow a minimum clearance of 0.030 inches (0.76 mm) around the entire perimeter of the drive for cooling. • Use only M3 UNC mounting screws. • Do not overtighten the mounting screws (maximum torque: 4.0 inch-lb). • Four (4) threads (0.

4.3.1 Identify Device command The Identify Device command (command code ECH) transfers information about the drive to the host following power up. The data is organized as a single 512-byte block of data, whose contents are shown in the table on page 27. All reserved bits or words should be set to zero. Parameters listed with an “x” are drive-specific or vary with the state of the drive. See Section 2.0 on page 3 for default parameter settings.
Word Description Value 57–58 Current capacity in sectors xxxxH 59 Number of sectors transferred during a Read Multiple or Write Multiple command xxxxH 60–61 Total number of user-addressable LBA sectors available (see Section 2.
Word Description Value 95–99 ATA-reserved 0000H 100– 103 Total number of user-addressable LBA sectors available (see Section 2.2 for related information) These words are required for drives that support the 48-bit addressing feature. Maximum value: 0000FFFFFFFFFFFFh.
4.3.2 Set Features command This command controls the implementation of various features that the drive supports. When the drive receives this command, it sets BSY, checks the contents of the Features register, clears BSY and generates an interrupt. If the value in the register does not represent a feature that the drive supports, the command is aborted. Power-on default has the read look-ahead and write caching features enabled.
4.3.3 S.M.A.R.T. commands S.M.A.R.T. provides near-term failure prediction for disc drives. When S.M.A.R.T. is enabled, the drive monitors predetermined drive attributes that are susceptible to degradation over time. If self-monitoring determines that a failure is likely, S.M.A.R.T. makes a status report available to the host. Not all failures are predictable. S.M.A.R.T. predictability is limited to the attributes the drive can monitor. For more information on S.M.A.R.T.
