Western Digital Se WD4000F9YZ 4TB 7.2K 3.5 inch 6 Gb/s Enterprise SATA Hard Drive - New Pull
Datacenter Capacity HDD
Optimal Storage for NAS and Scale-Out Architectures
WD’s Se hard drives provide an ideal solution for scaleout datacenters, delivering a cost-effective combination of performance, reliability, and workload capability while maintaining the hardiness of a true enterprise-class design. 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, multi-generation platform, with over 28 million terabytes of enterprise-class storage shipped*, WD understands reliable high-quality products are the backbone of your datacenter investment.
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.
Twice the processing power to maximize performance.
RAFF™ rotational vibration cancellation technology
Enhanced 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 errorrecovery (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.
This hard drive is compatible with: Windows 8/7/Vista/XP/2000, Windows Server, Linux, and Mac OS X.
