Vibration Protection
Enhanced RAFFâ„¢ technology uses sophisticated electronics to monitor the drive and correct linear and rotational vibrations in real time for improved performance versus WDâ€s desktop drives in high-vibration environments.

RAID-specific, time-limited error recovery (TLER)
Time-limited error recovery helps to reduce drive fallout within a storage environment caused by the extended hard drive error-recovery processes common to desktop drives.

Dynamic fly height technology
Each read-write headâ€s fly height is adjusted in real time to ensure consistent performance for reduced errors and optimized reliability.

COMPATIBILITY TESTING
All WD Gold hard drives are extensively tested across a variety of popular OEM storage systems, SATA controllers, and host bus adapters, to ensure ease of integration for a plug and play solution.
