4TB 7.200 rpm 3.5" SATA SE Datacenter
WD's Se datacenter capacity HDD is an ideal solution for scale-out datacenters, delivering a cost-effective combination of performance, reliability, and workload capability, while maintaining the hardiness of a true enterprise-class design. The Se is best suited for bulk cloud storage, replicated environments, content delivery networks (CDNs), SMB to high-end network attached storage (NAS), backup and archiving.
All WD datacenter storage devices are designed from the ground up to deliver optimal performance and maximum data integrity while running 24x7x365 in demanding multi-slot environments.
A pedigree in enterprise. WD, 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.
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.
Dual processor Twice the processing power to maximize performance.
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.
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.
StableTrac™. 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.
RAID-specific, time-limited error recovery (TLER). Prevents drive fallout caused by the extended hard drive error-recovery processes common to desktop drives.
NoTouch™ ramp load technology. The recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit.
Thermal extended burn-in test. Each drive is put through extended burn-in testing with thermal cycling to ensure reliable operation.
Dynamic fly height technology. Each read-write head's fly height is adjusted in real time for optimum reliability.
