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 users to install a Serial ATA host adapter and Serial ATA disk drive in the current system and expect all of the existing applications to work as normal.

The Serial ATA interface connects each disk drive in a point-to-point configuration with the Serial ATA host adapter. There is no master/slave relationship with Serial ATA devices like there is with parallel ATA. If two drives are attached to one Serial ATA host adapter, the host operating system views the two devices as if they were both “masters” on two separate ports. This essentially means both drives behave as if they are Device 0 (master) devices.

Note: The host adapter may, optionally, emulate a master/slave environment to host software where two devices on separate Serial ATA ports are represented to host software as Device 0 (master) and Device 1 (slave) accessed at the same set of host bus addresses. A host adapter that emulates a master/slave environment manages two sets of shadow registers. This is not a typical Serial ATA environment.

The Serial ATA host adapter and drive share the function of emulating parallel ATA device behavior to provide backward compatibility with existing host systems and software. The Command and Control Block registers, PIO and DMA data transfers, resets, and interrupts are all emulated.

The Serial ATA host adapter contains a set of registers that shadow the contents of the traditional device registers, referred to as the Shadow Register Block. All Serial ATA devices behave like Device 0 devices. For additional information about how Serial ATA emulates parallel ATA, refer to the “Serial ATA: High-Speed Serialized AT Attachment” specification. The specification can be downloaded from www.serialata.org.

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 following drive models:

Specification summary tables

The specifications listed in the following tables are for quick reference. For details on specification measurement or definition, see the appropriate section of this manual.

Table 1 Drive specifications summary

One GB equals one billion bytes when referring to hard drive capacity. Accessible capacity may vary depending on the operating environment and formatting. See Section 2.11, “Reliability” for rated MTBF device operating condition requirements.

Formatted capacity

One GB equals one billion bytes when referring to hard drive capacity. Accessible capacity may vary depending on the operating environment and formatting.

LBA mode

When addressing these drives in LBA mode, all blocks (sectors) are consecutively numbered from 0 to n–1, where n is the number of guaranteed sectors as defined above. See Section 4.3.1, “Identify Device command” (words 60-61 and 100-103) for additional information about 48-bit addressing support of drives with capacities over 137GB.

Recording and interface technology

Start/stop times

Power specifications
The drive receives DC power (+5V or +12V) through a native SATA power connector. See Figure 2.

Power consumption
Power requirements for the drives are listed in Table 2. Typical power measurements are based on an average of drives tested, under nominal conditions, using 5.0V and 12.0V input voltage at 25°C ambient temperature.

During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase acoustic and power to operational levels.

Table 2 DC power requirements (8TB)

Typical current profiles

8TB Typical 12V startup and operation current profile

Conducted noise

Input noise ripple is measured at the host system power supply across an equivalent 80-ohm resistive load on the +12 V line or an equivalent 15-ohm resistive load on the +5V line.

• Using 12V power, the drive is expected to operate with a maximum of 120mV peak-to-peak square-wave injected noise at up to 10MHz.
• Using 5V power, the drive is expected to operate with a maximum of 100mV peak-to-peak square-wave injected noise at up to 10MHz.

Note Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write current.

Voltage tolerance

Voltage tolerance (including noise): 5V +10/ -5% 12V ± 10%

Extended Power Conditions – PowerChoice

Utilizing the load/unload architecture a programmable power management interface is provided to tailor systems for reduced power consumption and performance requirements. The table below lists the supported power conditions available in PowerChoice.

Power conditions are ordered from highest power consumption (and shortest recovery time) to lowest power consumption (and longest recovery time) as follows: Idle_a power >= Idle_b power >= Idle_c power >= Standby_z power. The further users go down in the table, the more power savings is actualized. For example, Idle_b results in greater power savings than the Idle_a power condition. Standby results in the greatest power savings.

Each power condition has a set of current, saved, and default settings. Default settings are not modifiable. Default and saved settings persist across power-on resets. The current settings do not persist across power-on resets. At the time of manufacture, the default, saved, and current settings are in the Power Conditions log match.

PowerChoice is invoked using one of two methods

• Automatic power transitions are triggered by the expiration of individual power condition timers. These timer values may be customized and enabled using the Extended Power Conditions (EPC) feature set using the standardized Set Features command interface.
• Immediate host-commanded power transitions may be initiated using an EPC Set Features “Go to Power Condition” subcommand to enter any supported power condition. Legacy power commands Standby Immediate and Idle Immediate also provide a method to directly transition the drive into supported power conditions.

PowerChoice exits power-saving states under the following conditions

• Any command which requires the drive to enter the PM0: Active state (media access)
• Power on reset

PowerChoice provides the following reporting methods for tracking purposes

Check Power Mode Command

• Reports the current power state of the drive

Identify Device Command

• EPC Feature set a supported flag
• EPC Feature enabled flag is set if at least one Idle power condition timer is enabled

Power Condition Log reports the following for each power condition

• Nominal recovery time from the power condition to active
• If the power condition is Supported, Changeable, and Savable
• Default enabled state, and timer value
• Saved enabled state, and timer value
• Current enabled state, and timer value

S.M.A.R.T. Read Data Reports

• Attribute 192 – Emergency Retract Count
• Attribute 193 – Load/Unload Cycle Count

PowerChoice Manufacture Default Power Condition Timer Values

Default power condition timer values have been established to assure product reliability and data integrity. A minimum timer value threshold of two minutes ensures the appropriate amount of background drive maintenance activities occurs. Attempting to set timer values less than the specified minimum timer value threshold will result in an aborted EPC “Set Power Condition Timer” subcommand.

Setting power condition timer values less than the manufacturer-specified defaults or issuing the EPC “Go to Power Condition” subcommand at a rate exceeding the default timers may limit this product’s reliability and data integrity.

Environmental limits

Temperature and humidity values experienced by the drive must be such that condensation does not occur on any drive part. Altitude and atmospheric pressure specifications are referenced to a standard day at 58.7°F (14.8°C).

Note To maintain optimal performance drives should be run at nominal drive temperatures and humidity. See Section 2.11, “Reliability” for rated MTBF device operating condition requirements.

Temperature

• a.Operating
  41°F to 158°F (5°C to 70°C) drive case temperature range with a maximum temperature gradient of 36°F (20°C) per hour. The maximum allowable drive case temperature is 140°F (60°C). Airflow may be required to achieve consistent nominal drive temperature values (see Section 3.4). To confirm that the required cooling is provided for the electronics and HDA, place the drive in its final mechanical configuration, and perform random write/read operations. After the temperatures stabilize, monitor the current drive temperature using the SMART temperature attribute 194 or Device Statistics log 04h.
• b.Non-operating
  –40° to 158°F (–40° to 70°C) package ambient with a maximum gradient of 36°F (20°C) per hour. This specification assumes that the drive is packaged in the shipping container designed by Seagate for use with the drive.

Humidity
The values below assume that no condensation on the drive occurs. The maximum wet bulb temperature is 84.2°F (29°C).

Relative humidity

Effective Altitude (sea level)

Shock and Vibration

Shock and vibration measurements specified in this document are made directly on the drive itself and applied in the X, Y, and Z axis at the drive mounting point locations.
Shock

• a.Operating
  The drive will operate without error while subjected to intermittent shock pulses not exceeding 70 Gs (read) and 40 Gs (write) at a maximum duration of 2ms.
• b.Non-operating
  The drive will operate without non-recoverable errors after being subjected to shock pulses not exceeding 300g at a maximum duration of 2ms.

Vibration

a.Linear Random Operating Vibration
The drive will operate without non-recoverable errors while being subjected to the random power spectral density noise specified below.

b.Random Rotary Operating Vibration
The drive will exhibit greater than 90% throughput for sequential and random write operations while subjected to the shaped random power spectral density noise specified below.

c.Linear Random Non-Operating Vibration
The drive will not incur physical damage or have non-recoverable errors after being subjected to the power spectral density noise specified below.

Acoustics

Drive acoustics are measured as overall A-weighted acoustic sound power levels (no pure tones). All measurements are consistent with ISO document 7779. Sound power measurements are taken under essentially free-field conditions over a reflecting plane. For all tests, the drive is oriented with the cover facing upward.

Note For seek mode tests, the drive is placed in seek mode only. The number of seeks per second is defined by the following equation: (Number of seeks per second = 0.4 / (average latency + average access time

Table 3 Fluid Dynamic Bearing (FDB) motor Acoustics

During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase acoustic and power to operational levels.

Test for Prominent Discrete Tones (PDTs)
Seagate follows the ECMA-74 standards for the measurement and identification of PDTs. An exception to this process is the use of the absolute threshold of hearing. Seagate uses this threshold curve (originated in ISO 389-7) to discern tone audibility and to compensate for the inaudible components of sound prior to the computation of tone ratios according to Annex D of the ECMA-74 standards.

Electromagnetic immunity
When properly installed in a representative host system, the drive operates without errors or degradation in performance when

subjected to the radio frequency (RF) environments defined in the following table:

Table 4 Radiofrequency environments

Reliability

Annualized Failure Rate (AFR) and Mean Time Between Failures (MTBF)

The production disk drive shall achieve an annualized failure rate of 0.87% (MTBF of 1,000,000 hours) over a 5-year service life when used in Enterprise Storage field conditions as limited by the following:

• 8760 power-on hours per year.
• HDA temperature as reported by the drive <= 40°C
• Ambient wet bulb temp <= 26°C
• Typical workload
• The AFR (MTBF) is a population statistic not relevant to individual units

ANSI/ISA S71.04-2013 G2 classification levels and dust contamination to ISO 14644-1 Class 8 standards (as measured at the device) The MTBF specification for the drive assumes the operating environment is designed to maintain nominal drive temperature and humidity. Occasional excursions in operating conditions between the rated MTBF conditions and the maximum drive operating conditions may occur without significant impact on the rated MTBF. However continual or sustained operation beyond the rated MTBF conditions will degrade the drive MTBF and reduce product reliability.

Table 6 Taiwan – Restricted Substances

Corrosive environment

Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years of exposure to light industrial environments containing sulfurous gases, chlorine, and nitric oxide, classes G and H per ASTM B845. However, this accelerated testing cannot duplicate every potential application environment.

Users should use caution exposing any electronic components to uncontrolled chemical pollutants and corrosive chemicals as electronic drive component reliability can be affected by the installation environment. The silver, copper, nickel, and gold films used in hard disk drives are especially sensitive to the presence of sulfide, chloride, and nitrate contaminants. Sulfur is found to be the most damaging. Materials used in cabinet fabrication, such as vulcanized rubber, that can outgas corrosive compounds should be minimized or eliminated. The useful life of any electronic equipment may be extended by replacing materials near circuitry with sulfide-free alternatives.

Seagate recommends that data centers be kept clean by monitoring and controlling dust and gaseous contamination. Gaseous s contamination should be within ANSI/ISA S71.04-2013 G2 classification levels (as measured on copper and silver coupons), and dust contamination to ISO 14644-1 Class 8 standards, and MTBF-rated conditions as defined in the Annualized Failure Rate (AFR) and Mean Time Between Failure (MTBF) section.

Product Warranty

Beginning on the date of shipment to the customer and continuing for the period specified in the purchase contract, Seagat e warrants that each product (including components and subassemblies) that fails to function properly under normal use due to defect in materials or workmanship or due to nonconformance to the applicable specifications will be repaired or replaced, at Seagate’s option and at no charge to the customer, if returned by the customer at customer’s expense to Seagate’s designated facility in accordance with Seagate’s warranty procedure. Seagate will pay for transporting the repair or replacement item to the customer.

For more detailed warranty information, refer to the standard terms and conditions of purchase for Seagate products on the purchase documentation. The remaining warranty for a particular drive can be determined by calling Seagate Customer Service at 1-800-468-3472. Users can also determine the remaining warranty using the Seagate website (www.seagate.com). The drive serial number is required to determine the remaining warranty information.

Shipping

When transporting or shipping a drive, use only a Seagate-approved container. Keep the original box. Seagate-approved containers are easily identified by the Seagate Approved Package label. Shipping a drive in a non-approved container voids the drive warranty. Seagate repair centers may refuse receipt of components improperly packaged or obviously damaged in transit. Contact the authorized Seagate distributor to purchase additional boxes. Seagate recommends shipping by an air-ride carrier experienced in handling computer equipment.

Storage

Maximum storage periods are 180 days within the original unopened Seagate shipping package or 60 days unpackaged within the defined non-operating limits (refer to the environmental section in this manual). Storage can be extended to 1 year packaged or unpackaged under optimal environmental conditions (25°C, <40% relative humidity non-condensing, and non-corrosive environment). During any storage period, the drive’s non-operational temperature, humidity, wet bulb, atmospheric conditions, shock, vibration, magnetic, and electrical field specifications should be followed.

Product repair and return information

Seagate customer service centers are the only facilities authorized to service Seagate drives. Seagate does not sanction any third-party repair facilities. Any unauthorized repair or tampering with the factory seal voids the warranty.

Configuring and mounting the drive

This section contains the specifications and instructions for configuring and mounting the drive.

Handling and static-discharge precautions

After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic discharge (ESD) hazards. Observe the following standard handling and static-discharge precautions:

• Before handling the drive, put on a grounded wrist strap, or ground oneself frequently by touching the metal chassis of a computer that is plugged into a grounded outlet. Wear a grounded wrist strap throughout the entire installation procedure.
• Handle the drive by its edges or frame only.
• The drive is extremely fragile—handle it with care. Do not press down on the drive top cover.
• Always rest the drive on a padded, antistatic surface until mounting it in the computer.
• Do not touch the connector pins or the printed circuit board.
• Do not remove the factory-installed labels from the drive or cover them with additional labels. Removal voids the warranty. Some factory-installed labels contain information needed to service the drive. Other labels are used to seal out dirt and contamination.

Configuring the drive

Each drive on the Serial ATA interface connects point-to-point with the Serial ATA host adapter. There is no master/slave relationship because each drive is considered a master in a point-to-point relationship. If two drives are attached to one Serial ATA host adapter, the host operating system views the two devices as if they were both “masters” on two separate ports. Both drives behave as if they are Device 0 (master) devices.

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 in). 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. The drive and the host receptacle incorporate features that enable the direct connection to be hot-pluggable and blind-mateable.

For installations that require cables, users can connect the drive as illustrated in Figure 2.

Each cable is keyed to ensure correct orientation. IronWolf SATA drives support latching SATA connectors.

Drive mounting

Users can mount the drive in any orientation using four screws in the side-mounting holes or four screws in the bottom-mounting holes. See Figure 3 for drive mounting dimensions. Follow these important mounting precautions when mounting the drive:

• Allow a minimum clearance of 0.030 in (0.76mm) around the entire perimeter of the drive for cooling.
• Use only 6-32 UNC mounting screws.
• The screws should be inserted no more than 0.140 in (3.56mm) into the bottom or side mounting holes.
• Do not overtighten the mounting screws (maximum torque: 6 in-lb).

Mechanical specifications

Refer to Figure 3 for detailed mounting configuration dimensions. See “Drive mounting”. Weight: 8TB models

• Note These dimensions conform to the Small Form Factor Standard documented in SFF-8301 and SFF-8323, found at www.sffcommittee.org

• Note The image is for mechanical dimension reference only and may not represent the actual drive.

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. For detailed information about the Serial ATA interface, refer to the “Serial ATA: High-Speed Serialized AT Attachment” specification.

Hot-Plug compatibility
IronWolf SATA drives incorporate connectors that enable users to hot plug these drives in accordance with the Serial ATA Revision 3.2 specification. This specification can be downloaded from www.serialata.org.

Caution The drive motor must come to a complete stop (Ready to spindle stop time indicated in Section 2.4) prior to changing the plane of operation. This time is required to insure data integrity.

Serial ATA device plug connector pin definitions

Table 7 summarizes the signals on the Serial ATA interface and power connectors.

Table 7 Serial ATA connector pin definitions

Notes:

1. All pins are in a single row, with a 1.27mm (0.050”) pitch.
2. The comments on the mating sequence apply to the case of the backplane blind mate connector only. In this case, the mating sequences are:
   • the ground pins P4 and P12.
   • the pre-charge power pins and the other ground pins.
   • the signal pins and the rest of the power pins.
3. There are three power pins for each voltage. One pin from each voltage is used for pre-charge when installed in a blind-mate backplane configuration.
4. All used voltage pins (Vx) must be terminated. Seagate IronWolf SATA Product Manual, Rev. B

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”. for details and subcommands used in the S.M.A.R.T. implementation.

Table 8 Supported ATA commands

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 Table 8. 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 for default parameter settings.

The following commands contain drive-specific features that may not be included in the Serial ATA specification.

Note See the bit descriptions below for words 63, 84, and 88 of the Identify Drive data.

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 writes caching features enabled. The acceptable values for the Features register are defined as follows

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 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. commands and implementation, see the Draft ATA-5 Standard.

SeaTools diagnostic software activates a built-in drive self-test (DST S.M.A.R.T. command for D4H) that eliminates unnecessary drive returns. The diagnostic software ships with all new drives and is also available at: http://www.seagate.com/support/downloads/seatools/.

This drive is shipped with S.M.A.R.T. features disabled. Users must have a recent BIOS or software package that supports S.M.A.R.T. to enable this feature. The table below shows the S.M.A.R.T. command codes that the drive uses.
