The 3 TB Hard Drive Kit for 6TB and 12TB WD Sentinel DX4000 Small Office Storage Servers from WD upgrades the storage capacity of your WD Sentinel DX4000 Small Office Storage Server. The kit comes with one WD RE4-GP EP500M Hard Drive. Its advanced power management technology delivers a faster and a greener solution for large-scale data centers. The hard drive features 64 MB cache, dual processors and increased areal density that gives twice the processing power results. The IntelliPower technology provides a fine-tuned balance of spin speed, transfer rate and caching algorithms to deliver significant power savings and solid performance. The IntelliSeek feature calculates optimum seek speeds, thereby reducing power consumption, noise and vibration. The IntelliPark technology automatically unloads recording heads when idle to reduce aerodynamic drag. It automatically invokes idle mode whenever possible to further reduce unnecessary power consumption. The StableTrac function firmly secures the motor shaft at both ends to minimize system-induced vibration and stabilizes the platters for accurate tracking. With Time-Limited Error Recovery (TLER) function, this hard drive prevents drive fallout caused by extended hard drive error-recovery processes. The Rotary Acceleration Feed Forward (RAFF) feature optimizes operation and performance in vibration-prone and multi-drive systems such as rack-mounted servers.
Improvements in the power-conserving technologies such as IntelliSeek, IntelliPark and IntelliPower, deliver improved power consumption over the previous generation drive.
Improved Rotary Vibration Tolerance
Advanced mechanical optimizations along with system characterization and validation provide high performance under vibration conditions.
With 1.2 million hours MTBF, this drive has the highest available reliability rating on a high-capacity drive.
A fine-tuned balance of spin speed, transfer rate and caching algorithms is designed to deliver significant power savings and solid performance. Additionally, this drive features WD GreenPower Technology, which consumes less current during start up, allowing more drives to spin up simultaneously. This results in faster system readiness.
IntelliSeek calculates optimum seek speeds to lower unnecessary power consumption, noise and vibration.
Delivers low power consumption by disengaging read/write channel electronics. It also automatically unloads recording heads during idle to reduce aerodynamic drag.
Active Power Management
The hard drive features WD GreenPower Technology that monitors the work load and automatically invokes idle mode whenever possible to further reduce unnecessary power consumption. The drive recovery time from idle mode is less than one second, which provides seamless power management between the drive and the host controller.
Perpendicular Magnetic Recording (PMR)
The PMR technology achieves greater areal density.
StableTrac secures the motor shaft at both ends, that reduces system-induced vibration and stabilizes the platter 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 which are common to desktop drives.
Rotary Acceleration Feed Forward (RAFF)
Optimizes operation and performance when the drive is used in vibration-prone and multi-drive systems such as rack-mounted servers.
