1.1.1About 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.
NOTEThe 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.or

1.2.5.4Extended 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.

Reduced electronics
Heads unloaded. Disks spinning at full RPM
Heads unloaded. Disks spinning at reduced RPM
Heads unloaded. Motor stopped (disks not spinning)
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 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)

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.
Power Condition NameManufacturer Default Timer Values
Idle_a100 ms
Idle_b2 min
Idle_c4 min
Standby_z15 min
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.
