When referring to drive capacity, one gigabyte, or GB, equals one billion bytes and one terabyte, or TB, equals one trillion bytes. Your
computer’s operating system may use a different standard of measurement and report a lower capacity. In addition, some of the listed
capacity is used for formatting and other functions, and thus will not be available for data storage. Actual quantities will vary based on
various factors, including file size, file format, features and application software. Actual data rates may vary depending on operating
environment and other factors. The export or re-export of hardware or software containing encryption may be regulated by the U.S.

Note Seagate recommends validating the configuration with the selected HBA/RAID
controller manufacturer to ensure use of full capacity is supported.
Note Previous generations of Seagate Self-Encrypting Drive models were called Full
Disk Encryption (FDE) models before a differentiation between drive-based
encryption and other forms of encryption was necessary
Note The Self-Encrypting Drive models indicated on the cover of this product manual
have provisions for “Security of Data at Rest” based on the standards defined by
the Trusted Computing Group (see www.trustedcomputinggroup.org).

Seagate Enterprise Capacity 2.5 HDD v3 SATA Product Manual, Rev. D 7
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 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 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.
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.
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 SerialATA environment.

2.5 Power specifications
The drive receives DC power (+5V and +12V) through a native SATA power connector. See Figure 4 on page 25.
2.5.1 Power consumption
Power requirements for the drives are listed in Table 2 and Table 3. 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.
Operation at 3 Gb mode reduces the +5V supply load by 3mA with a commensurate power reduction of 15mW.
*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.
Note There is no measurable impact to the 12V supply load when running at lower interface speeds.

2.5.4 Power-management modes
The drive provides programmable power management to provide greater energy efficiency. In most systems, the user can
control power management through the system setup program. The drive features the following power-management modes:
•Active mode
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 disk 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 toActive mode any
time disk access is necessary.
• Sleep mode
The drive enters Sleep mode after receiving a Sleep command from the host. In Sleep mode, the drive buffer 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 count-
ing 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 disk access is necessary.

Idle_a ID Biased Rotating Enabled

Idle_c Parked Rotating at lower RPM Enabled

2.5.5 Extended Power Conditions - PowerChoiceTM
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 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" sub-
command 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 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

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 occur.
Attempting to set a 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 products reliability and data integrity.
