DESCRIPTION AND FEATURES
General Description
Western Digital Ultrastar Capac ity Enterprise hard drives offer up to 10 TB capacities and are available
with SATA interface. With the highest error tolerance and MTBF of any capacity-optimized drive,
Western Digital Ultrastar deliver s the durability and reliability required in tightly packed vibration prone
multi-drive systems. The combination of high-capacity, peak performance and robust design make
Western Digital Ultrastar drives ideal for heavy workload environments, cloud storage, RAID arrays,
external storage arrays, data warehousing, and mining applications.
Product Features
Serial ATA (SATA) — Serial ATA (SATA) is the next generation bus interface for hard drives. It is
designed to replace Parallel ATA, and has many advantages including increased transfer rate,
improved signal integrity, enhanced data protection, and hot plug support.
Time-Limited Error Recovery (TLER) — TLER prevents hard drive error recovery fallout by
limiting the time the drive spends in error recovery, providing increased performance, improved
availability, and lower total cost of ownership in RAID arrays.
Rotary Acceleration Feed Forward (RAFF) — These drives employ RAFF technology to maintain
hard drive performance in high vibration environment s through adap t ive compensat i on of the servo
system.
Perpendicular Magnetic Recording (PMR) — With PMR technology the magnetization of each
data bit is aligned vertically to the sp inning disk, ra ther than longitudinally as has been the case in
hard drive technology for decades. This enables more data on a given disk than is possible with
conventiona l longitudinal recording, a nd provides a p l atform for futur e expansion of hard drive
densities.
IntelliSeek™ — Key product feature that calculates optimum seek speeds to lower power
consumption, noise, and vibration.
Native Command Queuing (NCQ) — Performance of a random I/O workload can be improved
through intelligent re-ordering of the I/O requests so they read/write to and from the nearest available
sectors and minimize the need for additional disk revolutions or head actuator movement. This
improvement can be achieved though Native Command Queing (NCQ) , which is supp orted by these
hard drives .
Pre-emptive Wear Leveling (PWL) — This feature provides a solution for protecting the recording
media against mechanical wear. In cases where the drive is so busy with incoming commands that it
is forced to stay in a same cylinder position for a long time, the PWL control engine initiates forced
seeks so that disk lubricant maintains an even distribution and does not become depleted. This feature
ensures reliability for applications that perform a high incidence of read/write operations at the same
physical location on the disk.
MicroFemto Slider — These drives incorporate the next generation of femto slider form factor in
which the read/write head is mounted o n the small, lightweight microfemto slider that all ows the head
to move more quickly from track to track on the disk.
S.M.A.R.T. Command Transport (SCT) — The SCT Command Transport feature set provides a
method for a host to send commands and data to a device and for a device to send data and status to a
host using log pages.
World Wide Name (WWN) — The World Wide Name (WWN) defined in ATA/ATAPI-7 is a
modification of the IEEE extended unique identifier 64 bit standard (EUI-64) and is comprised of three
major components: naming authority, organizationally unique id e ntifie r (OUI) and serial number.
This product’s OUI is 0014EEh.

Data Lifeguard data protection utilities include thermal management, an environ mental protection
system, and embedded error detection and repair features that automatically detect, isolate, and
repair problem areas that may develop over the extended use of the hard drive. With these enhanced
data reliability features, the drive can perform more accurate monitoring, error repair, and deliver
exceptional data security.

CacheFlow™
CacheFlow is the unique, multi-generation disk caching system. It incorporates read cache with write
cache.
CacheFlow was designed to obtain maximum performance with today’s most popular operating s yste ms
and applications. CacheFlow increases performance over prior caching algorithms by increasing the
number of times that requested data is in the cache. This reduces the number of host commands that
require actual media access thereby improving overall drive performance.
Typical applications perform a variety of access patterns, such as random, sequential, and repetitive.
CacheFlow is designed to dynamically adapt to the changes in access patterns that occur during the course
of application execution.
Random mode is the default operational mode for CacheFlow. Once CacheFlow detects a sequential access
pattern, it leaves random mode. CacheFlow also performs predictive read operations to increase the
probability that data requested in fut ure c ommands already exists in the cache.
CacheFlow partitions the buff e r into multiple segments to allow for the fact that applica tions may access
multiple non-contiguous areas on the disk. CacheFlow tracks the amount of valid data in each segment
and controls the deallocation of segments to maximize drive performance.
Write Cache
CacheFlow is designed to improve both single and multi-sector write performance by reducing delays
caused by seek time and rotational latency.
The write cache adaptively detects random and sequential access patterns during application execution.
If a defective sector is found during a write cache operation, that sector is automatically relocated before the
write occurs.
Read Cache
CacheFlow implements a multiple segment read cache. Cache segments are assigned to read commands as
they are received from the host.
Each read segment consists of pre and post read sectors in addition to the host-requested sectors. This
maximizes the amount of cache data in the drive’s buffer, thereby increasing the likelihood of cache hits and
improving o verall performance.

Use either the four bottom screws or at least four of the side mounting screws to rigidly suppo rt the drive
and prevent vibration. Some adaptor frames may not have the mechanical design structure capable of
mounting the drive to meet the specified shock and vibration requirements.
The hard drive itself does not pr ovide electrical isolation between mounting locations and drive ground
connection. If electrical isolation is required, the system designer or integrator would be responsible for
providing a s olution.
If your system does not support hot pl ugg in g (se e “ Hot Plug Support on page.25), it must be turned off and
unplugged before installing your hard drive.
Physical Dimensions
Drive Mounting
You can mou nt the hard drive in the X, Y, or Z axis, depending upon the physi cal design of your system.
For best results, mount the drive with all four screws grounded to the cha s s is. If all four screws are not
used, see "Grounding" on page.12.
The hard drive should be mounted to the chassis using four 6-32 screws. Recommended screw torque is 5
in-lb. Maximum screw torque is 10 in-lb.
CAUTION: Screws that are too long can damage the hard drive. Hard drive screw penetration
can differ between products depending upon hard drive design. Western Ditigal’s minimum
design criteria is to always meet the SFF 8301 industry standard specification. The industry
standard as defined in the SFF 8301 specifies a maximum of 3 mm screw penetration, and for a
minimum of 2.4 mm of thread engagement from both the screw and the hard drive.
See Figure 1
for allowable fastener penetration for this product family.
The PCBA and HDA grounds are always connected together in the drive and cannot be disconnected. The
drive mounting screws, unless intentionally isolated, will provide additional ground connections between
the HDA and the system chassis. If the drive isn't grounded via mounting screws as described
Drive Installation” on Page.46, there may be increased electrical emissions (EMI).

Power Savings Modes
This product is capable of supporting both legacy ATA Advanced Power Management (APM) mode and
the new more extensive Extended Power Conditions (EPC) standards. Unless otherwise specified, the
default disk drive is shipped with the EPC mode enabled, and the legacy APM modes can be enabled via
the Set Feature command (Feature ‘4A’h, Sub Command ‘04’h). These two power savings
implementations are exclusively used, and thus not simultaneously supported.
This drive supports the legacy ATA power management commands that lower the average power
consumption of the hard drives. For example, to take advantage of the lower power consumption modes
of the drive, an energy efficient host system could implement a power management scheme that issues a
Standby Immediate command when a host resident disk inactivity timer expires. The Standby Immediate
command causes the drive to spin down and enter a low-power mode. Subsequent disk access commands
would cause the drive to spi n up and execute the new command. To avoid excessive wear on the drive due
to the starting and stopping of the HDA, set the host’s disk inactivity timer to no shorter than ten minutes.
Hard Disk Drive
Technical Reference Manual

Ultrastar DC HA210
Western Digital drives additionally support T13 Extended Power Conditions, as stated in the ACS-2
specification. Power savings features, normally only available in notebook drives, are now included in our
Enterprise products. With these features enabled, drive power can be reduced automatically via inactivity
timer, or manually via Host command. In timer based mode, the drive automatically starts reducing its
power based on inactivity of co mma nd s from the Host. With progression into the idle states, the drive
saves more and more power, but consequently takes longer to recover and respond to Host media
commands.
A summary of the new low power modes and what the drive does in each mode is shown below:
Idle_A

<10 ms recovery
Idle_B
Heads Parked

Standby_y recovery can use full spin up power.
Standby_Z

Drive not spinning
Recovery is similar to a typical TTR (Time To Ready) for the HDD
Western Digital has added the Power Condition Log, which defines the support, enable bits, and timers
for all power conditions. The power management timers start running after a ll Host commanded drive
activity is complete, and will run during drive background operations, but do not take effect until those
background operations are completed. The timer expiration min/max values are visible to the Host/
Initiator, but are rounded silently by the drive to its internal min/max values. The timer enable and timer
values can be marked independently as changeable. Please note that some Host Operating Systems may
be unable to take advantage of the inactivity timers, as they constantly access the Drive with writes to
update a time stamp. In these situatio ns it is advisable to extend the Idle_B ti mer value beyond the time
interval of the writes, or to disab le the timer entirely. Please see your Western Digital representative for
help with questions about these features .

Operating Vibration
Drives are tested by applying a random excitation in each linear axis, one axis at a time. The drive incurs
no physical damage and no hard errors while subjected to continuous vibration not exc eeding the leve l
listed in Table 3 Operating performance may degrade during periods of exposure to continuous vibration.
Non- Operating Vibration
Note: This specification applies to handling and transportation of unmounted drives.
Drives are tested by applying a random excitation in each linear axis, one axis at a time. The drive incurs
no physical damage when subjected to continuous vibration not exceeding the level listed in Table 3.
Packaged Shock and Vibration
The shipping packaging is designed to meet the National/International Safe T ransit Association (N/ ISTA)
standards for packaged products. The drive incurs no physical damage when subjected to the N/ ISTA
standards.
