With advanced technology that delivers consistent high performance in a multitude of applications, & with ten times the workload capability of desktop drives, WD Re is the workhorse of the WD's datacenter portfolio. WD Re is perfect for high-availability storage arrays that demand the most robust storage device available. High performance, capacity & reliability make WD Re ideal for data warehousing/mining & high-performance computing. High capacity Nearline drive - Massive capacities up to 6 TB suit even the most demanding datacenter, enterprise server, or cloud storage needs. Designed for high-intensity applications - Designed to handle up to 550 TB per year – the highest workload capability of any 3.5-inch hard drive – delivering both performance & reliability to any datacenter environment. Designed for durability & reliability - With up to 1.4 million hours MTBF, this high performance drive delivers the highest level of reliability for 24x 7x 365 operation in the most demanding storage environments. Designed for quality & reliability - Datacenter drives undergo at least 5 million hours of functional testing, & over 20 million hours of comprehensive Interoperability testing in an extensive array of server & storage systems. Please see the product AVL list on our website for more information. Dual processor - Twice the processing power to maximize performance. Stable Trac™ – The motor shaft is secured at both ends to reduce system-induced vibration & stabilize platters for accurate tracking during read & write operations. Multi-axis shock sensor – Automatically detects the subtlest shock events & compensates to protect the data. Vibration Protection - Enhanced RAFF™ technology
Includes:: sophisticated electronics to monitor the drive & correct both linear & rotational vibration in real time. The result is a significant performance improvement in high vibration environments over the previous generation of drives. RAID-specific, time-limited error recovery (TLER) – Prevents drive fallout caused by the extended hard drive error-recovery processes common to desktop drives. No Touch™ ramp load technology – The recording head never touches the disk media ensuring significantly less wear to the recording head & 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. 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. (2 TB & above)
