Western Digital WD1502FYPS Operation manual

WD RE4-GP
Power-Saving Hard Drives
Available in capacities up to 2 TB, WD RE4-GP SATA hard drives
offer data-hungry organizations massive capacity with significant
power savings and lower cost of ownership compared to
competitors’ standard enterprise-class drives. These drives are
designed with WD GreenPower Technology™to deliver power
savings as the primary attribute and are equipped with 64 MB
cache, dual processors, and IntelliPower™, a fine-tuned balance
of spin speed, transfer rate, and caching algorithms designed to
deliver both significant power savings and solid performance.

world.
Faster
Massive 64 MB cache, dual processors,
and increased areal density yield twice
the processing power which results in up
to 25 percent performance improvement
over the previous generation.
Greener
Improvements in our power-conserving
technologies — IntelliSeek™,
IntelliPark™, and IntelliPower™— deliver
improved power consumption over our
previous generation of WD RE-GP drives.
Improved rotary vibration
tolerance
Optimized drive mechanics, system
characterization, and process validation
yields unmatched performance in high
vibration environments.
Lower total cost of ownership
Large data-hungry financial institutions
and web service providers can save up to
$10 savings per drive per year in
electricity costs (U.S). A large data center
with 10,000 drives could realize up to
$100,000 in savings per year.
24x7 reliability
With 1.2 million hours MTBF, these drives
have the highest available reliability rating
on a high-capacity drive.
Product Benefits
Product Features
IntelliPower
A fine-tuned balance of spin speed,
transfer rate, and caching algorithms
designed to deliver both significant power
savings and solid performance.
Additionally, drives with WD GreenPower
Technology consume less current during
start up allowing more drives to spin up
simultaneously resulting in faster system
readiness.
IntelliSeek
Calculates optimum seek speeds to lower
unnecessary power consumption, noise,
and vibration.
IntelliPark
Delivers lower power consumption by
automatically unloading recording heads
during idle to reduce aerodynamic drag,
and by disengaging read/write channel
electronics.
Active Power Management
Drives with WD GreenPower Technology
monitor the work load and automatically
invoke idle mode whenever possible to
further reduce unnecessary power
consumption. Drive recovery time from
idle mode is less than one second,
providing seamless power management
between the drive and the host controller.
StableTrac™
Secures the motor shaft at both ends to
reduce system-induced vibration and
stabilize platters for accurate tracking
during read and write operations.
RAID-specific time-limited error
recovery (TLER)
Pioneered by WD, this feature prevents
drive fallout caused by the extended hard
drive error-recovery processes common
to desktop drives.
Rotary Acceleration Feed
Forward (RAFF™)
Optimizes operation and performance
when the drives are used in vibration-
prone multi-drive systems such as
rackmounted servers.

1As used for storage capacity, one megabyte (MB) = one million bytes, one gigabyte (GB) = one billion bytes, and one terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environment. As used for buffer or cache, one megabyte (MB) = 1,048,576
bytes. As used for transfer rate or interface, megabyte per second (MB/s) = one million bytes per second, and gigabit per second (Gb/s) = one billion bits per second. Effective maximum SATA 3 Gb/s transfer rate calculated according to the Serial ATA specification published by the SATA-
IO organization as of the date of this specification sheet. Visit www.sata-io.org for details.
2WD hard drive products manufactured and sold worldwide after June 1, 2006, meet or exceed Restriction of Hazardous Substances (RoHS) compliance requirements as mandated by the European Union for electrical and electronic products. The RoHS Directive 2002/95/EC of the
European Parliament, which is effective in the EU beginning July 1, 2006, aims to protect human health and the environment by restricting the use of certain hazardous substances in new equipment, and consists of restrictions on lead, mercury, cadmium, and other substances.
