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 normally 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 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 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 http://www.serialata.org.

2.7 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.

Table 4 Typical seek times

SEEK TIMES (MSEC) READ

Track-to-track (typical) 1
Average (typical) 14
Full-stroke (max) 30
Average latency 5.56

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.

MOMENTUS 5400.6 SATA PRODUCT MANUAL, REV. G 11

2.9 POWER SPECIFICATIONS

The drive receives DC power (+5V) through a native SATA power connector.

2.9.1 Power consumption

Power requirements for the drives are listed in the table on page

12. Typical power measurements are based on an average

of drives tested, under nominal conditions, 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 is measured based on three random seek
operations every 100 msecs. This mode is not typical.

• Read/write power and current

Read/write power is measured with the heads on track, based on three 63 sector read or write operations every 100 msecs.

• 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 model

*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.

**Standby power is measured at steady state (after 200ms from transition)

2.9.1.1 Typical current profile

Figure 1. Typical +5V only startup and operation current profile

2.9.2 Deferred spinup

Momentus 5400.6 SATA drives do not support the deferred spinup option. If you require this option, refer to the Momentus

5400.3 SATA Blade Server family of drives.

2.9.3 Conducted noise

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

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

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

2.9.4 Voltage tolerance

Voltage tolerance (including noise):
5V ± 5%

MOMENTUS 5400.6 SATA PRODUCT MANUAL, REV. G 13

2.9.5 Power-management modes

The drive provides programmable power management to provide greater energy efficiency. In most systems, you can control
power management through the system setup program. The drive features the following power-management modes:

Table 6 Power management modes

POWER MODES HEADS SPINDLE BUFFER

Active (operating) Tracking Rotating Full power
Idle, performance Tracking Rotating Self refresh—low power
Idle, active Floating Rotating Self refresh—low power
Idle, low power Parked Rotating Self refresh—low power
Standby Parked Stopped Self refresh—low power
Sleep Parked Stopped Self refresh—low power

• 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 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 in Self Refresh
Low Power mode, 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 buffer is in Self
Refresh Low Power mode, 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.

restricts the presence of chemical substances, including Lead, Cadmium, Mercury, Hexavalent Chromium, PBB and PBDE,
in electronic products, effective July 2006. This drive is manufactured with components and materials that comply with the
RoHS Directive..

2.15.2 China Restriction of Hazardous Substances (RoHS) Directive

This product has an Environmental Protection Use Period (EPUP) of 20 years. The following table contains
information mandated by China's "Marking Requirements for Control of Pollution Caused by Electronic
Information Products" Standard.

chemical substances. A new law, the European Union Restriction of Hazardous Substances (RoHS) Directive,

"O" indicates the hazardous and toxic substance content of the part (at the homogenous material level) is lower than the
threshold defined by the China RoHS MCV Standard.

"X" indicates the hazardous and toxic substance content of the part (at the homogenous material level) is over the threshold
defined by the China RoHS MCV Standard.

2.16 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, chloride, 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 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.

3.0 CONFIGURING AND MOUNTING THE DRIVE

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

3.1 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:

Caution:

• Keep the drive in the electrostatic discharge (ESD) bag until you are ready for installation to limit the drive’s exposure to ESD.

• 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 only by its edges or frame.

• The drive is 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.

3.2 CONFIGURING THE DRIVE

Each drive on the Serial ATA interface connects in a point-to-point configuration with the Serial ATA host adapter. There is no
master/slave relationship because each drive is considered a master in a point-to-point relationships. 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 means both drives behave as if they are Device 0 (master) devices.

Serial ATA drives are designed for easy installation. It is normally not necessary to set any jumpers on this drive for proper
operation. If the host system does not support SATA 3Gb/s operation, place a jumper on pins 1 and 2 to limit the drive to

1.5Gb/s operation.

3.3 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 inches). See Table 9 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 3.

Each cable is keyed to ensure correct orientation.

3.4 DRIVE MOUNTING

You can mount the drive using four screws in the side-mounting holes or four screws in the bottom-mounting holes. See
Figure Figure 4. for drive mounting dimensions. Follow these important mounting precautions when mounting the drive:

• Allow a minimum clearance of 0.030 inches (0.76 mm) around the entire perimeter of the drive for cooling.

• Use only M3 UNC mounting screws.

• Do not overtighten the mounting screws. Maximum torque: 4.0 inch-lb (0.4519 N-m).

• Four (4) threads (0.080 inches, 2.032 mm) minimum screw engagement recommended.

• Avoid excessive drive distortion when mounting. Refer to the following specifications for stiffness/deflection information:

TOP COVER STIFFNESS/DEFLECTION

4.0 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. The drive also supports the use of
the IORDY signal to provide reliable high-speed data transfers.

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

4.1 HOT-PLUG COMPATIBILITY

Momentus 5400.6 SATA drives incorporate connectors which enable you to hot plug these drives in accordance with the
Serial ATA: High Speed Serialized AT Attachment specification revision 2.0. This specification can be downloaded from http:/
/www.serialata.org. This device requires a COMRESET from the host after a hotplug event.

4.3.3 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 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-8 Standard.

SeaTools diagnostic software activates a built-in drive self-test (DST S.M.A.R.T. command for D4

) that eliminates

H

unnecessary drive returns. The diagnostic software ships with all new drives and is also available at:

http://seatools.seagate.com.

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.
