Publication Disclaimer Information

One MB is equal to one million bytes, one GB is equal to one billion bytes and one TB equals 1,000GB (one trillion bytes)
when referring to storage capacity. Accessible capacity will vary from the stated capacity due to formatting and partitioning

of the drive, the computer’s operating system, and other factors.

Fixed disk subsystem description

Control Electronics

The drive is electronically controlled by a microprocessor, several logic modules, digital/analog modules, and
various drivers and receivers. The control electronics performs the following major functions:

 Controls and interprets all interface signals between the host controller and the drive.
 Controls read write accessing of the disk media, including defect management and error recovery.
 Controls starting, stopping, and monitoring of the spindle.
 Conducts a power-up sequence and calibrates the servo.
 Analyzes servo signals to provide closed loop control. These include position error signal and estimated

velocity.

 Monitors the actuator position and determines the target track for a seek operation.
 Controls the voice coil motor driver to align the actuator in a desired position.
 Constantly monitors error conditions of the servo and takes corresponding action if an error occurs.
 Monitors various timers such as head settle and servo failure.
 Performs self-checkout (diagnostics).

Head disk assembly

The head disk assembly (HDA) is assembled in a clean room environment and contains the disks and actuator
assembly. Helium is constantly circulated and filtered when the drive is operational. No venting of the HDA is
accomplished, as HDA is hermetically sealed.

The spindle is driven directly by an in-hub, brushless, sensorless DC drive motor. Dynamic braking is used to
quickly stop the spindle.

Actuator

The read/write heads are mounted in the actuator. The actuator is a swing-arm assembly driven by a voice coil
motor. A closed-loop positioning servo controls the movement of the actuator. An embedded servo pattern supplies
feedback to the positioning servo to keep the read/write heads centered over the desired track.

The actuator assembly is balanced to allow vertical or horizontal mounting without adjustment.
When the drive is powered off, the actuator automatically moves the head to the actuator ramp outside of the disk

where it parks.

Notes:

Logical layout: Logical layout is an imaginary drive parameter (that is, the number of heads) which is used to
access the drive from the system interface. The Logical layout to Physical layout (that is, the actual Head and
Sectors) translation is done automatically in the drive. The default setting can be obtained by issuing an IDENTIFY
DEVICE command

Drive Format

Upon shipment from HGST manufacturing the drive satisfies the sector continuity in the physical format by means
of the defect flagging strategy described in Section 5 on page 14 in order to provide the maximum performance to
users.

Cylinder allocation

Physical cylinder is calculated from the starting data track of 0. It is not relevant to logical CHS. Depending on the
capacity some of the inner zone cylinders are not allocated.

Data cylinder
This cylinder contains the user data which can be sent and retrieved via read/write commands and a spare area for
reassigned data.

Spare cylinder
The spare cylinder is used by HGST manufacturing and includes data sent from a defect location.

Performance characteristics

Drive performance is characterized by the following parameters:

 Command overhead
 Mechanical positioning

- Seek time

- Latency

 Data transfer speed
 Buffering operation (Look ahead/Write cache)

All the above parameters contribute to drive performance. There are other parameters that contribute to the
performance of the actual system. This specification defines the characteristics of the drive, not the characteristics
of the system throughput which depends on the system and the application.

Command overhead

Command overhead is defined as the time required

 from the time H->D Reg FIS w/ command bit is sent by host
 to the time

 PIO Set Up FIS is sent by device(PIO Read/Write)
 DATA FIS is sent by device(DMA Read)
 DMA Activate FIS is sent by device(DMA Write)
 DMA Set Up FIS is sent by device(NCQ Read/Write)
 Seek Start (Read cache not hit or Seek)

The table below gives average command overhead.

The terms “Typical” and “Max” are used throughout this specification with the following meanings:

Typical. The average of the drive population tested at nominal environmental and voltage conditions.
Max. The maximum value measured on any one drive over the full range of the environmental and voltage

conditions. (See Section 6.2, “Environment” and Section 6.3, “DC Power Requirements”)

skip

Media defects are remapped to the next available sector during the Format Process in manufacturing. The mapping
from LBA to the physical locations is calculated by an internally maintained table.

Shipped format

 Data areas are optimally used.
 No extra sector is wasted as a spare throughout user data areas.
 All pushes generated by defects are absorbed by the spare tracks of the inner zone.

Figure 1 PList physical format

Defects are skipped without any constraint, such as track or cylinder boundary. The calculation from LBA to
physical is done automatically by internal table.

Connector location

Refer to the following illustration to see the location of the connectors.

Figure 2 Connector location

Signal Connector

The drive uses the standard 29 pin Serial Attached SCSI (SAS) connector which conforms to the mechanical
requirements of SFF 8660. The connector is expected to be used in an environment which uses a common
connector structure for racking disk drives in a cabinet. The connector allows for plugging a drive directly into a
backplane by providing the necessary electrical connection. Mechanical stability and device retention must be
provided by a mechanism outside the drive.
