Overview
INVEST IN GOLD
Featuring up to ten times the workload capacity of desktop drives, WD Gold™
hard drives are designed from the ground up for enterprise-class reliability,
capacity, power efficiency and performance.
High workload rating
Delivering dependable performance to any storage
environment, WD Gold hard drives are designed with a workload rating up to 550TB
per year,* among the highest of any 3.5-inch hard drive.
Enterprise-class storage to rely
on
With up to 2.5 million hours MTBF,
WD Gold hard drives deliver reliability and durability, are built for yearly
operation (24x7x365) within the most demanding storage environments, and are
backed with a 5 year limited warranty.
HelioSeal Technology
Featured in over 15 million Western Digital hard
drives shipped, HelioSeal technology allows for higher capacities and less
turbulence on large storage arrays. And now on its 4thgeneration
design, HelioSeal technology is field-tested and proven to deliver high
capacity, reliability, and power efficiency you can trust.
VIBRATION
PROTECTION
Enhanced RAFF technology uses
sophisticated electronics to monitor the drive and correct linear and rotational
vibrations in real time for improved performance versus WDs desktop drives in
high-vibration environments.
RAID-SPECIFIC, TIME-LIMITED ERROR RECOVERY
(TLER)
Time-limited error recovery helps to reduce drive
fallout within a storage environment caused by the extended hard drive
error-recovery processes common to desktop drives.
DYNAMIC FLY HEIGHT TECHNOLOGY
Each read-write heads fly height is adjusted in
real time to ensure consistent performance for reduced errors and optimized
reliability.
COMPATIBILITY TESTING
All WD Gold hard drives are extensively tested
across a variety of popular OEM storage systems, SATA controllers, and host bus
adapters, to ensure ease of integration for a plug and play solution.
