Western Digital 3TB Enterprise Hard Drive for WD Sentinel - WDBBDN0030HNC-NASN

As demand for Storage continues to expand, the need for more efficient power solutions becomes paramount. WD T3 enterprise SATA hard drives make it possible for large-scale Data centers to increase storage capacity without exceeding available power, and in many cases actually reducing power consumption. WD T3 drives help combat the four major challenges large data installations face - total drive slots, maximum capacity, power allotment, and financial constraints - while lowering the total cost of ownership. Upgrade the storage capacity on your WD Sentinel small office storage server. This drive kit contains one WD RE4-GP EP500M drive, compatible with WD Sentinel server.

Features

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.

Greener - Improvements in our power-conserving technologies - IntelliSeek, IntelliPark, and IntelliPower - deliver improved power consumption over previous generation of WD RE-GP drive.

Improved Rotary vibration tolerance - Advanced mechanical optimizations along with system characterization and validation provide the highest performance under vibration conditions of any WD product.

Lower total cost of ownership - Large data-hungry organizations such as financial institutions and Web service providers may realize up to $10 savings per drive per year in electricity costs (U.S.). A large data center with 10,000 drives could realize up to $100,000 in savings per year.

24x7 reliability - With 1.2 million hours MTBF, these drives have the highest available reliability rating on a high-capacity drive.

Active Power Management - Drives with WD GreenPower Technology Monitor the 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.

Perpendicular Magnetic Recording (PMR) - Employs PMR technology to achieve even greater areal density.

StableTrac - Secures the motor shaft at both ends to reduce system-induced vibration and stabilize platters for accurate tracking, during read and write operations.

RAID-specific time-limited error recovery (TLER) - Pioneered by WD, this feature prevents drive fallout caused by the extended hard drive error-recovery processes common to Desktop drives.

Rotary Acceleration Feed Forward (RAFF) - Optimizes operation and performance when the drives are used in vibration-prone multi-drive systems such as rack mounted servers.
