Momentus 5400.6 SATA Product Manual, Rev. E 1

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 installatio n.

• 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 content s of the traditio nal device regi s­ters, 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 aver age of all

• Average seek time is a true statistical random aver a

possible single-track seeks in both directions.

ge of at least 5,000 measurements of seeks between

random tracks, less overhead.

Seek times (msec) Read

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

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.

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 11. 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 towar

d a specific position on the disc surface and does
not execute a read or write operation. Servo electr on ics a re active . Seek m ode p ower is measur ed based on
three random seek operations every 100 msecs. This mode is not typical.

• Read/write
Read/write power is measured with the heads on track, base

power and current

d on three 63 sector read or write operations

every 100 msecs.

• Idle mode power

Idle mode power is measured with the drive up to spee

d, 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

2.9.2 Deferred spinup

Momentus 5400.6 SATA drives do not support the defe rred spin

up 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 powe r

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. Equ

ivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write

current.

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 comma nd 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.

2.15 Environmental protection

Seagate designs its products to meet environmental protection requirements worldwide, including regulations
restricting certain chemical substances.

2.15.1 European Union Restriction of Hazardous Substances (RoHS)

Seagate designs its products to meet environmental protection
restricting certain chemical substances. A new law, the European Union Restriction of Hazardous Substances
(RoHS) Directive, 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

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 exposin g any electronic c omponents 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 th e most damaging . In additio n, electronic component s
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 gr ou nd e d wrist strap, or ground yourself frequently by touching the metal
chassis of a computer that is plugged into a grounded outlet. Wea r 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.

Momentus 5400.6 SATA Product Manual, Rev. E 21

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 bo th drive s 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.

3.0 Gbits per second operation

Limit data transfer rate to

1.5 Gbits per second

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.

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 4 for drive mounting dimensions. Follow these important mounting precautions when mount­ing the drive:

• Allow a minimum clearance of 0.030 in

• 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 moun tin g. Refer to the

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.
