About the WD Gold 22TB Enterprise Class SATA HDD 3.5-inch 7200RPM
The WD Gold 22TB Enterprise Class SATA HDD (WD221KRYZ) is a 3.5-inch hard drive engineered to meet the rigorous demands of enterprise data centers, cloud infrastructure, and scale-out storage environments. Built on Western Digital's helium-sealed platform with CMR (Conventional Magnetic Recording) technology, it delivers consistent, reliable throughput at 7200 RPM across sustained, high-duty-cycle workloads. The drive is rated for up to 550 TB per year workload capacity, making it suitable for always-on production environments where data integrity and uptime are non-negotiable.
The WD Gold 22TB incorporates Western Digital's proprietary vibration compensation technology, including a dual-stage actuator and rotational vibration (RV) sensors, to maintain read/write stability in multi-drive chassis configurations such as dense JBODs and enterprise NAS enclosures. The drive supports a 512 MB cache buffer and connects via SATA 6 Gb/s interface. Its time-limited error recovery (TLER) firmware behavior is tuned specifically for RAID environments, preventing drive drop-out during array recovery operations.
Designed for 24×7 continuous operation, the WD Gold 22TB targets workloads that require high-capacity, long-duration sequential and random I/O, including AI training dataset repositories, large-scale video surveillance archives, enterprise backup and restore systems, and cloud object storage tiers. Omnixon Global supplies this drive to enterprise and institutional buyers across the UAE, GCC, EMEA, and APAC regions, supporting large-volume procurement for data center build-outs and storage refresh cycles.
Ideal for
- High-capacity cold and warm storage tiers in hyperscale and enterprise data centers requiring dense, cost-efficient per-terabyte footprint
- AI and machine learning infrastructure for storing large training datasets, model checkpoints, and inference logs at scale
- Enterprise backup and disaster recovery target storage within tape-replacement or disk-to-disk-to-cloud architectures
- Large-scale video surveillance repositories requiring continuous write workloads across 24×7 multi-stream recording environments
- Cloud object storage nodes and scale-out NAS deployments where RAID reliability, TLER support, and high workload ratings are mandatory
- Media and entertainment post-production archives storing high-resolution video assets, raw footage, and finished content at petabyte scale

Frequently Asked Questions about WD Gold 22TB Enterprise Class SATA HDD 3.5-inch 7200RPM
What workloads is the WD Gold 22TB Enterprise Class SATA HDD 3.5-inch 7200RPM designed for?
Enterprise mixed-use and ri workloads — including transactional databases, AI inference data, virtualisation, hyperconverged storage, and analytics. Endurance is rated for sustained 24/7 operation, not consumer-style burst use.
Will this SSD work in my Dell / HPE / Lenovo server?
Most enterprise SSDs ship in vendor-branded variants tied to a server QVL. Share your server model and we will quote the correctly-branded SKU (Dell-genuine, HPE-genuine, Lenovo-genuine) so support and firmware update tooling work without complaints.
Do you provide support support locally?
Yes. All units are sourced through distribution, so support registers cleanly with the manufacturer (Samsung / Kioxia / Solidigm / Micron / WD / Seagate) and DOA replacement is handled through our Dubai operations within 5 business days for UAE/GCC.
How do I get a quote for a bulk order?
Use the RFQ form on this page with your quantity and destination. For larger and project-scale orders we engage the vendor directly to prepare a tailored quote, and our pre-sales team follows up with a vendor-confirmed quote.
