WD Gold WD4002FYYZ 4TB 7200RPM 3.5inch 128MB SATA-6Gbps Datacenter HDD
Western Digital Gold WD4002FYYZ 4TB 7200RPM 3.5inch Large Form Factor 128MB Buffer SATA-6Gbps Datacenter Internal Hard Drive (5 Years Manufacturer Warranty)
Full range of nearline capacities
From entry-level servers to high end enterprise storage systems, WD Gold hard drives offer the capacities required for the most demanding datacenter environments.
High workload capability
Delivering both performance and reliability to any datacenter environment, WD Gold hard drives are designed to handle workloads up to 550TB per year which is among the highest workload capability of any 3.5-inch hard drive.
High level of reliability
With up to 2.5 million hours MTBF, WD Gold hard drives deliver one of the highest levels of reliability and durability for yearly operation (24x7x365) within the most demanding storage environments.
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.
RAID-specific, time-limited error recovery (TLER)
Reduces drive fallout caused by the extended hard drive error-recovery processes common to desktop drives.
Extended thermal 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.
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.
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.
WD Gold datacenter hard drives are launching with a new, high-capacity configuration of up to 8TB that offers HelioSeal® helium-technology for performance, ideal capacity per square foot, power efficiency and low power consumption for datacenter environments. WD Gold datacenter hard drives feature an optimized design with an 8TB option that helps reduce the TCO (Total Cost of Ownership) of servers and storage systems, benefiting IT administrators challenged with growing storage capacity needs on limited budgets. WD Gold hard drives will also include a premium dedicated support line for customers worldwide.
The Western Digital Gold WD4002FYYZ model internal Datacenter hard drive has a 3.5inch form factor and a 6Gbps external data transfer rate. It has a spindle speed of up to 7200RPM and a 4TB capacity. This Large Form Factor hard drive uses a SATA 6Gbps (Serial Advanced Technology Attachment) interface and has 5 Years Manufacturer Warranty.
