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. Department of

www.seagate.com Introduction
1.0 Introduction
This manual describes the functional, mechanical and interface specifications for the following:
Seagate® Exos® X24 SATA drive models.
These drives provide the following key features:
• 7200 RPM spindle speed.
• Fluid Dynamic Bearing motor
• Tri Stage Actuator
• 512MB Cache buffer
• Full-track multiple-sector transfer without local processor intervention.
• High instantaneous (burst) data-transfer rates (up to 600MB per second).
• Native Command Queuing with command ordering to increase performance in demanding applications.
• PowerChoice™ for selectable power savings
• Perpendicular recording technology provides the drives with increased areal density.
• SeaTools™ diagnostic software performs a drive self-test that eliminates unnecessary drive returns.

www.seagate.com Introduction
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.
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 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.

Power-on to ready time is based on typical operating conditions, default full current spin-up profile, and clean shutdown
prior to measurement. To ensure a clean shutdown a Flush Cache, Standby, or Standby Immediate command must be
completed before removal of interface power.
NOTE An unexpected power loss event, spin up at cold or hot temperature extremes
may cause the drive to exceed the typical and max time to ready by 5 seconds.
Extended time to ready is dependent on cache state and environmental
conditions prior to the unexpected power loss and during the subsequent power

2.5.4 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 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" subcom-
mand 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
Power Condition Name Power Condition ID Description
Idle_a 81H Reduced electronics
Idle_b 82H Heads unloaded. Disks spinning at full RPM
Idle_c 83H Heads unloaded. Disks spinning at reduced RPM
Standby_z 00H Heads unloaded. Motor stopped (disks not spinning)
