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 jump-  
ers 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 disc drive in your current  
system and expect all of your existing applications to work as normal.  
The Serial ATA interface connects each disc 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 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 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 a 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 regis-  
ters, referred to as the Shadow Register Block. All Serial ATA devices behave like Device 0 devices. For addi-  
tional information about how Serial ATA emulates parallel ATA, refer to the “Serial ATA: High Speed Serialized

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 5000 measurements of seeks between  
random tracks, less overhead.

Note. These drives are designed to consistently meet the seek times represented in this manual. Physical  
seeks, regardless of mode (such as track-to-track and average), are expected to meet the noted  
values. However, due to the manner in which these drives are formatted, benchmark tests that  
include command overhead or measure logical seeks may produce results that vary from these  
specifications.

Power specifications  
The drive receives DC power (+5V or +12V) through a native SATA power connector. See Figure 4 on page 26.  
3.8.1 Power consumption  
Power requirements for the drives are listed in the table on page 9. 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.  
• Spinup power  
Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating  
speed.  
• Seek mode  
During seek mode, the read/write actuator arm moves toward a specific position on the disc surface and  
does not execute a read or write operation. Servo electronics are active. Seek mode power represents the  
worst-case power consumption, using only random seeks with read or write latency time. This mode is not  
typical and is provided for worst-case information.  
• Read/write power and current  
Read/write power is measured with the heads on track, based on a 16-sector write followed by a 32-ms  
delay, then a 16-sector read followed by a 32ms delay.  
• Operating power and current  
Operating power is measured using 40 percent random seeks, 40 percent read/write mode (1 write for each  
10 reads) and 20 percent drive idle mode.  
• Idle mode power  
Idle mode power is measured with the drive up to speed, with servo electronics active and with the heads in  
a random track location.  
• Standby mode  
During Standby mode, the drive accepts commands, but the drive is not spinning, and the servo and read/  
write electronics are in power-down mode.

3.8.2 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.

The drive is in Active mode during the read/write and seek operations.  
• Idle mode  
The buffer remains enabled, and the drive accepts all commands and returns to Active mode any time disc  
access is necessary.  
Standby mode  
The drive enters Standby mode when the host sends a Standby Immediate command. If the host has set  
the standby timer, the drive can also enter Standby mode automatically after the drive has been inactive for  
a specifiable length of time. The standby timer delay is established using a Standby or Idle command. In  
Standby mode, the drive buffer is enabled, the heads are parked and the spindle is at rest. The drive  
accepts all commands and returns to Active mode any time disc access is necessary.  
• Sleep mode  
The drive enters Sleep mode after receiving a Sleep command from the host. In Sleep mode, the drive buf-  
fer is disabled, the heads are parked and the spindle is at rest. The drive leaves Sleep mode after it  
receives a Hard Reset or Soft Reset from the host. After receiving a reset, the drive exits Sleep mode and  
enters Standby mode with all current translation parameters intact.  
• Idle and Standby timers  
Each time the drive performs an Active function (read, write or seek), the standby timer is reinitialized and  
begins counting down from its specified delay times to zero. If the standby timer reaches zero before any  
drive activity is required, the drive makes a transition to Standby mode. In both Idle and Standby mode, the  
drive accepts all commands and returns to Active mode when disc access is necessary.

Extended Power Conditions - PowerChoiceTM  
Utilizing the load/unload architecture a programmable power management interface is provided to tailor sys-  
tems 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 you  
go down in the table, the more power savings is actualized. For example, Idle_b results in greater power sav-  
ings 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 which are triggered by 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 Imme-  
diate and Idle Immediate also provide a method to directly transition the drive into supported power condi-  
tions.  
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 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

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). Maximum wet bulb temperature is 82°F (28°C).  
3.9.1  
Temperature  
a. Operating  
The drive meets the operating specifications over a 41°F to 140°F (5°C to 60°C) drive case temperature  
range with a maximum temperature gradient of 36°F (20°C) per hour.  
The maximum allowable drive case temperature is 60°C. See Figure 3 for HDA case temperature  
measurement location  
The MTBF specification for the drive assumes the operating environment is designed to maintain nominal  
case temperature. The rated MTBF is based upon a sustained case temperature of 104°F (40°C).  
Occasional excursions in operating temperature between the rated MTBF temperature and the maximum  
drive operating case temperature may occur without impact to the rated MTBF temperature. However,  
continual or sustained operation at case temperatures beyond the rated MTBF temperature will degrade the  
drive MTBF and reduce product reliability.  
Air flow may be required to achieve consistent nominal case temperature values (see Section 4.4). To con-  
firm 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, measure the  
case temperature of the drive.  
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  
drive.

Acoustics  
Drive acoustics are measured as overall A-weighted acoustic sound power levels (no pure tones). All mea-  
surements 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)

Test for Prominent Discrete Tones (PDTs)  
Seagate follows the ECMA-74 standards for 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 computation  
of tone ratios according to Annex D of the ECMA-74 standards.

Reliability  
3.13.1  
Annualized Failure Rate (AFR) and Mean Time Between Failures (MTBF)  
The product shall achieve an Annualized Failure Rate (AFR) of 0.73% (MTBF of 1.2 million hours) when oper-  
ated nominal power and typical case temperatures of 40°C. Operation at temperatures outside the specifica-  
tions in Section 3.9 may increase the product AFR (decrease MTBF). AFR and MTBF are population statistics  
that are not relevant to individual units.  
AFR and MTBF specifications are based on the following assumptions for business critical storage system  
environments:  
• 8,760 power-on-hours per year.  
• Operations at nominal voltages.  
Temperatures outside the specifications in Section 3.9 may reduce thee product reliability.  
• Normal I/O duty cycle for enterprise nearline applications. Operation at excessive I/O duty cycle may  
degrade product reliability.  
The enterprise application nearline environment of power-on-hours, temperature, and I/O duty cycle affect the  
product AFR and MTBF.

Corrosive environment  
Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years 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 Seagate products are especially sensitive to the presence of sulfide, chlo-  
ride, and nitrate contaminants. Sulfur is found to be the most damaging. In addition, electronic components  
should never be exposed to condensing water on the surface of the printed circuit board assembly (PCBA) or  
exposed to an ambient relative humidity greater than 95%. Materials used in cabinet fabrication, such as vulca-  
nized 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.

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 dis-  
charge (ESD) hazards. Observe the following standard handling and static-discharge precautions:  
Caution:  
• Before handling the drive, put on a grounded wrist strap, or ground yourself 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 you mount 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.

4.2  
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 on 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.  
4.3  
Serial ATA cables and connectors  
The Serial ATA interface cable consists of four conductors in two differential pairs, plus three ground connec-  
tions. 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 which require cables, you can connect the drive as illustrated in Figure 4.

4.4  
Drive mounting  
You 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 5 for drive mounting dimensions. Follow these important mounting precau-  
tions 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 0.150 in (3.81mm) into the bottom or side mounting holes.  
• Do not overtighten the mounting screws (maximum torque: 6 in-lb).

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.  
5.1  
Hot-Plug compatibility  
Constellation ES Serial ATA drives incorporate connectors which enable you to hot plug these drives in accor-  
ata.org.  
Caution:  
The drive motor must come to a complete stop (Ready to spindle stop time indicated in Section 3.7)  
prior to changing the plane of operation. This time is required to insure data integrity.

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 inter-  
rupt. If the value in the register does not represent a feature that the drive supports, the command is aborted.

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 moni-  
tors 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 D4 ) that elimi-  
H
nates unnecessary drive returns. The diagnostic software ships with all new drives and is also available at:  
This drive is shipped with S.M.A.R.T. features disabled. You 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.
