Western Digital WDBBDN0030HNC-NASN Expansion 3TB 3.5in Hard Drive Kit For WD Sentinel NAS Server, IntelliPower, Bare Drive
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 DX4000.
Reduced power consumption. The combination of WD's IntelliSeek, NoTouch, and IntelliPower technologies brings optimized performance at industry-leading low power consumption; power is reduced as much as 40 percent.
Helps enable eco-friendly servers. Each WD T3 drive consumes an average of 4-5 watts less than competitor drives making it possible for energy-conscious customers to build servers with higher capacities, ensured reliability, and promote energy conservation.
Lower total cost of ownership. Large data-hungry financial institutions and web service providers can save up to $10 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.
IntelliPower. A fine-tuned balance of spin speed, transfer rate, and caching algorithms designed to deliver both significant power savings and solid performance. Additionally, WD GreenPower drives consume less current during start up allowing more drives to spin up simultaneously resulting in faster system readiness.
IntelliSeek. Calculates optimum seek speeds to lower unnecessary power consumption, noise, and vibration.
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.
Active Power Management. WD GreenPower drives 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.
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 rackmounted servers.
