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.

3.9.1.1 Typical current profile Figure 1. Typical +5V only startup and operation current profile 3.9.2 Deferred spinup Momentus 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 +5V 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 maximum 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 room 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 6: Drive A-weighted Sound Power Levels (SWL, BA) Idle* Seek 2.3 bels (typ) 2.5 bels (max) 2.4 bels (typ) 2.
3.13 Reliability Measurement type Specification Nonrecoverable read errors 1 per 1014 bits read, max. Annualized Failure Rate (AFR) <0.
Korean RRL If these drives have the Korean Communications Commission (KCC) logo, they comply with paragraph 1 of Article 11 of the Electromagnetic Compatibility control Regulation and meet the Electromagnetic Compatibility (EMC) Framework requirements of the Radio Research Laboratory (RRL) Communications Commission, Republic of Korea. These drives have been tested and comply with the Electromagnetic Interference/Electromagnetic Susceptibility (EMI/EMS) for Class B products.
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.
4.2 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.
4.4 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 0.030in (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 in-lb (0.4519 N-m). • Four (4) threads (0.080in, 2.
Measurements shown in Figure 4 are in inches. Figure 4. Mounting dimensions—top, side and end view 22 Momentus 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 the “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 ATA: High Speed Serialized AT Attachment specification. See “S.M.A.R.T. commands” on page 31.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 (for ST9640320AS, ST9500320AS, ST9320310AS, ST9250310AS and ST9160316AS models) or 4096-byte (for ST9640322AS, ST9320312AS and ST9400321AS models) block of data, whose contents are shown in the table on page 27. All reserved bits or words should be set to zero.
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 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 100–103 Total number of user-addressable LBA sectors available (see Section 3.2 for related information) These words are required for drives that support the 48-bit addressing feature. Maximum value: 0000FFFFFFFFFFFFh.
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 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.
