WD Gold 28TB Enterprise Class SATA HDD 3.5-inch 7200RPM

The WD Gold 28TB Enterprise Class SATA HDD (WD281KRYZ) is a 3.5-inch hard disk drive engineered specifically for demanding enterprise environments, including large-scale data centers, AI infrastructure, and high-capacity storage arrays. Built on Western Digital's HelioSeal helium-filled platform, the drive delivers sustained high-throughput performance at 7200 RPM across a massive 28TB native capacity, making it one of the highest-density drives in the WD Gold enterprise lineup. The helium-sealed enclosure reduces internal turbulence and power consumption while enabling the stacking of multiple platters without the thermal and mechanical penalties associated with air-filled designs.

Designed for continuous 24×7 operation, the WD Gold 28TB carries a rated workload of 550TB per year (TB/yr), reflecting its suitability for write-intensive and mixed enterprise workloads. The drive incorporates Western Digital's TLER (Time-Limited Error Recovery) technology, which is optimized for RAID environments by preventing individual drive timeouts from triggering unnecessary array rebuilds. Additional reliability features include vibration compensation through dual-stage actuator technology and an on-board rotational vibration (RV) sensor, both of which sustain read/write accuracy in multi-drive chassis configurations typical of enterprise NAS, SAN, and JBOD enclosures.

With a SATA 6 Gb/s interface and compatibility with standard 3.5-inch drive bays, the WD281KRYZ integrates readily into existing enterprise storage infrastructure without requiring proprietary connectivity. Its combination of high areal density, low idle power draw relative to capacity, and an MTBF rating of 2.5 million hours positions it as a reliable foundation for scale-out storage deployments supporting AI data lakes, surveillance repositories, backup and archival systems, and cloud storage nodes. Omnixon Global supplies the WD Gold 28TB to enterprise buyers across the UAE, GCC, EMEA, and APAC regions.

Ideal for

• High-capacity data center storage arrays and scale-out NAS enclosures requiring maximum per-spindle density with 24×7 continuous operation
• AI and machine learning infrastructure requiring large, fast-access data lakes for training dataset storage and retrieval
• Enterprise backup and disaster recovery repositories where high capacity and workload endurance are critical to meeting RTO and RPO targets
• Video surveillance and security storage platforms managing multi-stream, high-resolution footage archives over extended retention periods
• Cloud storage node deployments requiring dense, reliable SATA drives in high-vibration multi-drive chassis environments
• Enterprise RAID arrays and JBOD enclosures where TLER and RV sensor support are essential for array stability and sustained rebuild performance
