2.0 Introduction This manual describes the functional, mechanical and interface specifications for the following Seagate Momentus® Thin model drives: ST model # Part # Standard models ST320LT020 9YG142 ST250LT003 9YG14C ST160LT003 9YG141 These drives provide the following key features: • 5400-RPM spindle speed. • 16MB buffer. • Quiet operation. Fluid Dynamic Bearing (FDB) motor. • High instantaneous (burst) data-transfer rates (up to 3Gb/s). • Perpendicular recording technology.
2.1 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.
3.0 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 all models. 3.1 Specification summary table The specifications listed in this table are for quick reference.

3.8 Start/stop times Time to ready Typical Max @ 25°C Power-on to Ready (sec) 3.5 4.0 Standby to Ready (sec) 3.0 3.0 3.9 Power specifications The drive receives DC power (+5V) through a native SATA power connector. 3.9.1 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.
3.9.1.1 Typical current profile Figure 1. Typical +5V only startup and operation current profile 3.9.2 Deferred spinup Momentus Thin 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. 3.9.3 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.
3.9.5 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.
3.10 Environmental specifications 3.10.1 Ambient temperature Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. Above 1000 feet (305 meters), the maximum temperature is derated linearly by 1°C every 1000 feet. Operating: 0° to 60°C (32° to 140°F) Nonoperating: –40° to 70°C (–40° to 158°F) 3.10.
3.10.5 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. 3.10.5.1 Operating shock These drives comply with the performance levels specified in this document when subjected to a maximu m operating shock of 350 Gs based on half-sine shock pulses of 2ms. Shocks should not be repeated more than two times per second. 3.10.5.
3.11 Acoustics Drive emission of sound is measured consistent with the ECMA-74 and its’ referenced standards. Testing is conducted at r oom temperature (approximately 25°C). Emission levels are reported as the total A-weighted sound power levels for steady state, idle, and active seek modes of operation. Table 5: Drive A-weighted Sound Power Levels (SWL, BA) Idle* Performance seek 2.0 bels (typ) 2.2 bels (max) 2.2 bels (typ) 2.
3.13 Reliability Measurement type Specification Nonrecoverable read errors 1 per 1014 bits read, max Annualized Failure Rate (AFR) <0.
Australian C-Tick (N176) If these models have the C- Tick marking, they comply with the Australia/New Zealand Standard AS/NZ CISPR22 and meet the E lectromagnetic Compatibility (EMC) Framework requirements of the A ustralian Communication Authority (ACA). 3.14.3 FCC verification These drives are intended to be contained solely within a personal computer or similar enclosure (not attached as an external device).
3.15 Environmental protection Seagate designs its products to meet environmental protection requirements worldwide, including regulations restricting certain chemical substances. 3.15.1 European Union Restriction of Hazardous Substances (RoHS) The European Union Restriction of Hazardous Substances (RoHS) Directive, restricts the presence of chemical substances, including Lead, Cadmium, Mercury, Hexavalent Chromium, PBB and PBDE, in electronic products, effective July 2006.
4.0 Configuring and mounting the drive This section contains the specifications and instructions for configuring and mounting the drive. 4.1 Handling and static-discharge precautions After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic discharge (ESD) hazards.
4.3 Serial ATA cables and connectors The Serial ATA interface cable consists of four conductors in two differential pairs, plus three ground connections. The cable size may be 30 to 26 AWG with a maximum length of one meter (39.37 inches). See Table 7 for connector pin definitions. Either end of the SATA signal cable can be attached to the drive or host. For direct backplane connection, the drive connectors are inserted directly into the host receptacle.
Measurements shown in Figure 4 are inches and (mm). Figure 4. Mounting dimensions (for standard models) — top, side and end view Momentus Thin Product Manual, Rev.
5.0 Serial ATA (SATA) interface These drives use the industry-standard Serial ATA interface that supports FIS data transfers. It supports ATA programmed input/output (PIO) modes 0–4; multiword DMA modes 0–2, and Ultra DMA modes 0–6. The drive also supports the use of the IORDY signal to provide reliable high-speed data transfers. For detailed information about the Serial ATA interface, refer to th e “Serial ATA: High Speed Serialized AT Attachment” specification. 5.

5.3 Supported ATA commands The following table lists Serial ATA standard commands that the drive supports. For a detailed description of the ATA commands, refer to the Serial A TA: High Speed Serialized AT Attachment specification. See “S.M.A.R.T. commands” on page 28.for details and subcommands used in the S.M.A.R.T. implementation.

5.3.1 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. The following commands contain drive-specific features that may not be included in the Serial ATA specification.
Word Description Value 60–61 Total number of user-addressable sectors This field contains a value that is one greater than the total number of user-addressable sectors. The maximum value that shall be placed in this field is 0FFFFFFFh. The 0FFFFFFFh value applies to all capacities over 137GB (see Section 3.2 and 3.3 for related information).
Word Description Value 104–118 ATA-reserved 0000H 119 Free Fall Protection support (bit 5) 1 = Free Fall Protection supported 0 = Free Fall Protection not supported 120 Free Fall Protection enable/disable (bit 5) 1 = Free Fall Protection feature is enabled 0 = Free Fall Protection feature is disabled 121–127 ATA reserved 0000H 128 Security status 0021H 129–159 Seagate-reserved xxxxH 160–254 ATA-reserved 0000H 255 Integrity word xxA5H Note.
5.3.2 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.
5.3.3 S.M.A.R.T. commands S.M.A.R.T. provides near-term failure prediction for disk 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 st atus report available to the host. Not all failu res 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.
