HDD Western Digital 500GB 3.5" Serial ATA II WD RE4 7200 RPM
WD RE4 enterprise SATA hard drives combine 64 MB cache, dual processors and dual stage actuation to deliver high-performance storage suitable for demanding server and storage applications. These drives include technologies that reduce noise, improve positional accuracy, and protect data integrity while operating continuously.
The drive offers large capacity options up to 2 TB, dual-processor performance for faster throughput, and dual-actuator technology on the 2 TB model for improved head positioning. StableTrac and RAFF reduce vibration-related errors, while NoTouch ramp load and multi-axis shock sensors protect the recording heads and media. Additional features such as IntelliSeek, TLER for RAID environments, third-generation dynamic fly height, and Active Power Save optimize power consumption, reliability, and compatibility with enterprise systems.
Install the WD RE4 drive into a compatible enterprise SATA bay or server following the server manufacturer's installation procedure. Configure the drive in the system BIOS/RAID controller as required (for RAID use enable TLER-aware settings on the controller). Allow the system to complete any initialization and burn-in procedures. Use standard operating system tools to partition, format, and mount the drive. Monitor drive health and vibration-sensitive environments to take advantage of RAFF and StableTrac benefits.
Use the WD RE4 in enterprise servers and storage arrays where continuous 24x7 operation, vibration resilience, and RAID compatibility are required. For the 2 TB model, consider systems that can take advantage of dual stage actuation to maximize positional accuracy. Maintain regular backups and monitor SMART attributes for proactive maintenance.
