Western Digital RE4-GP 2TB SATA 64MB Cache 3.5 inch Hard Drive

Summary

This generation of WD RE-GP drives takes advantage of the performance improvements offered in our WD RE3 family of drives and adds advanced power management technology to deliver a faster, greener solution for large-scale data centres. Faster - 64 MB cache, dual processors, and increased areal density yield twice the processing power results in up to 25% performance improvement over the previous generation. Improvements in our power-conserving technologies - IntelliSeek, IntelliPark, and IntelliPower - deliver improved power consumption over our previous generation of WD RE-GP drive. Advanced mechanical optimizations along with system characterization and validation provide the highest performance under vibration conditions of any WD product. With 1.2 million hours MTBF, these drives have the highest available reliability rating on a high-capacity drive. A fine-tuned balance of spin speed, transfer rate, and caching algorithms designed to deliver both significant power savings and solid performance. Additionally, GreenPower drives consume less current during start up allowing more drives to spin up simultaneously resulting in faster system readiness.

Description

Calculates optimum seek speeds to lower unnecessary power consumption, noise, and vibration. Delivers lower power consumption by automatically unloading recording heads during idle to reduce aerodynamic drag, and by disengaging read/write channel electronics. WD drives with GreenPower technology monitor work load and automatically invoke idle mode whenever possible to further reduce unnecessary power consumption. Drive recovery time from idle mode is less than one second, providing seamless power management between the drive and the host controller. Employs PMR technology to achieve even greater areal density. Secures the motor shaft at both ends to reduce system-induced vibration and stabilize platters for accurate tracking, during read and write operations. Pioneered by WD, this feature prevents drive fallout caused by the extended hard drive error-recovery processes common to desktop drives. Optimizes operation and performance when the drives are used in vibration-prone multi-drive systems such as rack mounted servers. Ideal For: Large data centres, web service providers, commercial grade surveillance systems and organizations requiring huge amounts of storage with limited budget and power allotment.
