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 c onfiguration with tru e plug-and- play conn ectivity. 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 you to install a Ser ial ATA host adapter and Serial ATA disc drive in your cu rrent
system and expect all of your existing applications to work as normal.

The Serial ATA interface connects eac h disc drive in a point-to-point configu ration with the Serial ATA host
adapter. There is no master/slave relationship with Seria l ATA device s 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 essenti ally mean s both dr ives behav e as if they are Dev ice 0
(master) devices.

Note. The host ad apter may, optionally, emulate a master/slave environment to host software where two

devices on separate Serial ATA ports are represented to host so ftware as a Device 0 ( maste r) and
Device 1 (slave) acce ssed at the s ame set of ho st bus addr esses. A h ost adapter tha t emulat es a
master/slave environment manages two sets of shadow register s. This is not a typical Serial ATA
environment.

The Serial ATA host adapter and drive shar e the funct ion of emul ating para llel ATA device behavior to provid e
backward compatibility with existing host systems an d software. The Command and Contr ol 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 th e Shadow Register Block. A ll Se ri al ATA devices beh av e l ik e De vice 0 devices. For add i­tional information about how Ser ial ATA emulates parallel ATA, refer to the “Serial ATA: High Speed Serialized
AT Attachment” specification. The specification can be downloaded from http://www.serialata.com.

1.2 Native Command Queuing

Native Command Queuing (NCQ) is am ong the ad vanc ed featur es in troduced in the Se rial ATA II: Extensions
to Serial ATA 1.0 Specification. NCQ is a powerful technolo gy designed to increase pe rformance and endur­ance by allowing the drive to internally optimize the execution order of workloads. Intelligent reordering of com­mands within the drive’s internal command queue helps improve performance of queued workloads by
minimizing mechanical positioning latencies on the drive.

Operating systems suc h as Microsoft Windows and Linux are inc reasingl y taking advantage of multi- threade d
software or processor-based Hyper-Threading Technology. These features have a high potential to create
workloads where multiple commands are outstanding to the drive at the same time. By utilizing NCQ, the
potential disc performance is increased significantly for these workloads.

Native Command Queuing achieves high performance and efficiency through efficient command reordering. In
addition, there are three new capabilities that are built into the Serial ATA protocol to enhance NCQ perfor­mance: racefree status return, interrupt aggregation, and First-Party DMA.

2.6 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 rand om average of at least 5,000 measure ments of seeks between
random tracks, less overhead.

T able 3: Typical seek times

*Typical seek times (msec) Read Write

Track-to-track <1.0 <1.2
Average 8.5 9.5
Average latency 4.16 4.16

*Measured in performance mode
Note. These drives are designed to consistently meet the seek times represented in this manual. Physical

seeks, regardless of m ode (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 s eeks may produce results that vary from these
specifications.

2.7 Start/stop times

Power-on to Ready (sec) 10 (max)
Standby to Ready (sec) 10 (max)
Ready to spindle stop (sec) 10 (max)

2.8 Power specifications

The drive receives DC power (+5V or +12V) through a native SATA power connector. See Figure 4 on page 20.

2.8.1 Power consumption

Power requirements for the drives are listed in the table on page 9. Typical power measurements are based on
an average of drives tested, under nomi nal conditions, using 5.0 V and 12.0V input vo ltage at 25°C ambient
temperature.

• Spinup power

Spinup power is measured from the tim e of power-on to the ti me that the drive sp indle reaches ope rating
speed.

• Seek mode

During seek mode, the read/wr ite actuator arm moves towar d a specific position on the disc s urface and
does not execute a read or write o peration . Servo el ectroni cs are active. S eek mode po wer repr esen ts the
worst-case power co nsump tion, us ing o nly ran dom s eeks with read or wr ite la tency ti me. This mode is no t
typical and is provided for worst-case information.

• Read/write power and current

Read/write power is measured with the heads on track, ba sed on a 16- sector write fo llowed by a 32-msec
delay, then a 16-sector read followed by a 32-msec delay.

Barracuda 7200.7 Serial ATA Product Manual, Rev. N 7

• Operating power and current

Operating power is measured using 40 percent random seeks, 40 percent read/write mode (1 write for each
10 reads) and 20 percent drive idle mode.

• 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 accep ts co mmands, b ut the driv e is not spi nning , and the se rvo and read /
write electronics are in power-down mode.

2.8.2 Deferred spinup

Barracuda 7200.7 S erial ATA drives provide a deferred spi nup feature which storage sub system controllers
can use to sequence disc drive initializa tion. This is beneficial to systems which include m ultiple Serial ATA
hard disc drives beca use it allo ws subsystem c ontroll ers to stagger the spinup of ea ch drive to ac commodat e
available power supply current. This feature does not impact time-to-ready in typical desktop systems.

To accommodate the deferred spinup of multiple disc drives in an enclosure, Barracuda 7200.7 Serial ATA disc
drives will spin u p only after power is appl ied to the d rive and after s uccessful PHY (Physi cal layer) i nitializa­tion. PHY initialization occurs after the PHY enters the DP7:DR_Ready state. This state is reached after a suc-

Barracuda 7200.7 Serial ATA Product Manual, Rev. N 9

cessful exchange of Out-Of-Band (OOB) signals with a functional host-side Serial ATA port. In desktop
systems, SATA transceivers should initialize OOB as soon as power comes ready to guarantee the drive spins
up quickly. Seagate disc drives will not spin up without an operational host-side Serial ATA transceiver.

Additional details

Upon system power up, PHY commu nication is initiated with a COMRE SET signal, whic h is generated by the
host-side transcei ver. COMRESET is followed b y a COMINIT si gnal generated by t he disc drive tr ansceiver.
COMRESET and COMINIT a re follo w ed by an exchange of COMWAKE signals and Align pr im it iv es . The di sc
drive will spin up after the successful exchange of Align primitives cause the PHY to come ready.

For more details, refer to:

• Section 6.8 of the Serial ATA 1.0 High-Speed Serialized AT Attachment specification

• Section 6.2 of the Serial ATA II: Extensions to Serial ATA 1.0 specification

• SATA 1.0 design guides

Note. These specifications and guides are available on the Serial ATA web site (www.serialata.org).

2.8.3 Conducted noise

Input noise ripple is mea su red at the ho st system power supply acr o ss a n equ ival ent 80 -o hm r es isti ve load on
the +12 volt line or an equivalent 15-ohm resistive load on the +5 volt line.

• Using 12-volt power, the drive is expected to operate with a maximum of 120 mV peak-to-peak square-wave
injected noise at up to 10 MHz.

• Using 5-volt power, the drive is expect ed to ope rate wi th a maxi mum of 10 0 mV pe ak-t o-peak s quare- wave
injected noise at up to 10 MHz.

Note. Eq uivalent resistance is calculated by dividing the nom inal voltage by the typical RMS read/write

current.

2.8.5 Power-management modes

The drive provides programmab le power mana gement to provide grea ter energy efficiency. In most systems,
you can control power management through the system setup program. The drive features the following
power-management modes :

Power modes Heads Spindle Buffer

Active Tracking Rotating Enabled
Idle Tracking Rotating Enabled
Standby Parked Stopped Enabled
Sleep Parked Stopped Disabled

• Active mode
The drive is in Active mode during the read/write and seek operations.

• Idle mode
The buffer remains enable d, and the d rive ac ce pts all com man ds and ret urns to Ac ti ve mode any tim e di sc

access is necessary.

• Standby mode
The drive enters Standby mode whe n 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 le ngth of time. The standby timer delay is established usi ng a Standby or Idle command. I n
Standby mode, the drive buffer is enabled, 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 Sle ep command from the host. In Sleep mode, the drive
buffer is disabled, the heads are park ed and the spindle is at rest. The drive l eaves Sleep mode after it
receives a Hard Re se t or So ft Rese t from the ho st. A fter recei ving a res et, the drive exits Sl eep m ode an d
enters Standby mode with all current translation parameters intact.

• Idle and Standby timers

Each time the d rive perf orms an Ac tive fun ction (rea d, write or seek), the standb y timer is reini tialized and
begins counting dow n from its specified de lay times to zero. If the standby timer reac hes zero before any
drive activity is requir ed , the dr iv e m ake s 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.

2.9 Environmental specifications

2.14 Environmental protection

Seagate designs its prod ucts to meet environ mental protectio n requirem ents worldwide, in cluding regul ations
restricting certain chemical substances.

European Union Restriction of Hazardous Substances (RoHS)

The European Union Restriction of Hazardous Substances (RoHS) Directive restricts the presence of chemical
substances, including Lead (Pb), in electronic products effective July 2006. Although amendments to the
Euro-pean Union’s Restri ction of Hazardous Substances (Ro HS) Direc ti ve ha ve not bee n fin ali z ed, to th e bes t
of our knowledge the disc drives documented in this publication will comply with the final RoHS Directive
require-ments.

A number of parts and materials in Seag ate products are procured from external suppl iers. We rely on the
rep-resentations of our suppliers regarding the presence of RoHS substances in these parts and materials. Our
supplier contracts r equire compliance with our chem ical substance restrictions, a nd our suppliers document
their compliance with our requirements by providing material content declarations for all parts and materials for
the disc drives documented in this publication. Current supplier declarations include disclosure of the inclusion
of any RoHS-regulated substance in such parts or materials.

Seagate also has internal systems in place to ensure ongoing compliance with the RoHS Directive and all laws
and regulations which restrict chemical content in electronic products. These systems include standard
operat-ing procedures that ensure that restricted su bstances are not utiliz ed in our manufacturi ng operations,
labora-tory analyti cal validatio n testing, and an internal auditing pr ocess to ens ure that all standar d operatin g
procedures are complied with.

2.15 Corrosive environment

Seagate electronic driv e components pass accelerated corr osion testing equivalent to 10 ye ars exposure to
light industrial envir onments containi ng sulfuro us gases, chlorine an d 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 elec tronic drive componen t reliabi lity ca n be affected by th e installati on environm ent. The s ilver,
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, electr onic components
should never be ex pose d to c ondensin g water on the surfac e of th e pri nted cir cuit bo ard a ssembly (PCBA ) or
exposed to an ambient relative humidity greater than 95%. Materials used in cabinet fabrication, such as vulca­nized rubber, that can outgas corr osive compoun ds should be m inimized or e liminated. Th e useful life of any
electronic equipment may be extended by replacing materials near circuitry with sulfide-free alternatives.

Caution:

• The SeaShell™ replaces electrostatic discharge (ESD) bags. The SeaShell package is a shock-ribbed,

transparent clamshell enclosure that limits a drive’s exposure to ESD and also protects against external shocks
and stresses. The design permits attaching cables, software loading and label/barcode scanning without
removing the drive from the SeaShell. This minimizes handling damage. Keep the drive in the SeaShell
package until you are ready for installation.

• 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
instal lation procedure.

• Handle the drive by its edges or frame only.

• The drive is extremely 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 labe ls c ontain inf ormati on nee ded to s ervic e the d riv e. Oth er label s ar e

3.2 Configuring the drive

(

S

Each drive on the Serial ATA interface connects in a point-to-point configuration with the Serial ATA host
adapter. There is no master/slav e relationship because each drive is consider ed a master in a point-to-point
relationships. If two dr ives are attach ed on one Ser ial ATA host adapter, the host operating system vi ews 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 with no jumpers, terminators, or other settings. It is not nec­essary to set any jumpers on this drive for proper operation. The jumper block adjacent to the signal connector
is for factory use only.

Figure 3. Serial ATA connectors

SATA Power

3.3 Serial ATA cables and connectors

The Serial ATA interface cable consists of four conductors i n two differential pairs, plu s three ground co nnec­tions. The cable s ize may be 3 0 to 2 6 AWG with a m aximum length of on e m eter (3 9.37 inc hes). S ee Table 8
for connector pin definitions. Either end of the SATA signal cable can be attached to the drive or host.

For direct back plane co nnection , the dri ve connect ors ar e inserted directly into the h ost rec eptacle. The d rive
and the host recep tacle incorporate fe atures that enable the direct connec tion to be hot pl uggable and blin d
mateable.

For installations which require cables, you can connect the drive as illustrated in Figure 4.

3.4 Drive mounting

You can mount the drive in any o rientation u sing four s crews in the side -mountin g holes or four sc rews in th e
bottom-mounting holes. See Figure 5 on page 22 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 6-32 UNC mounting screws.

• The screws should be inserted no more than 0.150 inch (3.81 mm) into the bottom or side mounting holes.

• Do not overtighten the mounting screws (maximum torque: 6 inch-lb).

4.0 Serial ATA (SATA) interfac e

These drives use th e industr y-standard Serial ATA interface that sup ports FIS data transfe rs. It suppor ts 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 informa tion about the Serial ATA interface, refer to the “Serial ATA: High Speed Serialized AT
Attachment” specification.

4.1 Hot-Plug compatibility

Barracuda 7200.7 Serial ATA drives incorporate connectors which enable you to hot plug these drives in accor­dance with the Ser ial ATA: High Speed Serialized AT Attachment specificatio n revision 2. 0. This spec ification
