Datacenter Capacity HDD
WD Se datacenter capacity HDD is an ideal solution for scale-out architectures, delivering a cost-effective combination of performance, reliability, and workload capability, while maintaining the hardiness of a true enterprise-class design. WD Se is best suited for bulk cloud storage, replicated environments, content delivery networks (CDNs), large-scale network attached storage (NAS), backup and archiving.
Cost effective enterprise-class storage.
Get the right blend of performance, reliability and capacity and keep your total cost of ownership low.
Choose the storage foundation specifically designed for SMB to high-end NAS and large-scale datacenter replication environments running 24x7x365.
Maximum capacity for hyperscale environments.
Build a massive data footprint with capacities up to 4 TB - 144 TB per square foot.
A pedigree in enterprise
WD is one of the storage industry's pioneers and long-time leaders, has a rich history of manufacturing reliable enterprise storage at an affordable cost. Built on a time-tested platform, currently in its 6th generation, with over 28 million terabytes of enterprise-class storage shipped*, WD understands reliable high-quality products are the backbone of your datacenter investment.
*Quantity shipped reflected as of March 2013.
RAID-specific, time-limited error recovery (TLER).
Prevents drive fallout caused by the extended hard drive error-recovery processes common to desktop drives.
Designed for quality and reliability.
All drives undergo at least 5 million hours of functional testing, and over 20 million hours of additional testing under actual workloads in actual server and storage systems.
The motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking during read and write operations.
Multi-axis shock sensor.
Automatically detects the subtlest shock events and compensates to protect the data.
RAFF rotational vibration cancellation technology.
Enhanced Rotary Acceleration Feed Forward (RAFF) technology includes sophisticated electronics to monitor the drive and correct both linear and rotational vibration in real time. The result is a significant performance improvement in high vibration environments over the previous generation of drives.
Twice the processing power to maximize performance.
Dynamic fly height technology.
Each read-write head's fly height is adjusted in real time for optimum reliability.
Dual actuator technology.
A head positioning system with two actuators that improves positional accuracy over the data track(s). The primary actuator provides coarse displacement using conventional electromagnetic actuator principles. The secondary actuator uses piezoelectric motion to fine tune the head positioning to a higher degree of accuracy.
Thermal extended burn-in test.
Each drive is put through extended burn-in testing with thermal cycling to ensure reliable operation.
The Se is best suited for bulk cloud storage, replicated environments, content delivery networks (CDNs), SMB network attached storage (NAS), backup and archiving.
