Western Digital Hard drive WD121KRYZ 12TB Gold SATA 3.5 inch 7200RPM 256MB Cache Bare

Invest in Gold
Featuring up to ten times the workload capacity of desktop drives, WD Gold™ hard drives are designed from the ground up for enterprise-class reliability, capacity, power efficiency and performance.

Vibration Protection
Enhanced RAFF™ technology uses sophisticated electronics to monitor the drive and correct linear and rotational vibrations in real time for improved performance versus WD’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 head’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.
