The Drive That Runs the Cloud’s Cold Storage — And Just Made It Into the Enterprise Mainstream
The WD Gold 22TB is the same drive family that hyperscale data centers deploy by the tens of thousands for object storage, archive tiers, and backup repositories. It is not a NAS drive. It is not a desktop drive. It is a 24/7 enterprise data center drive with 2.5 million hours MTBF, 550 TB/year workload rating, and a 5-year warranty — now available at a price point that puts hyperscale-class storage economics within reach of mid-sized enterprises. With CMR recording (no SMR write penalty), helium sealing, and RV sensors, the Gold 22TB is the drive for environments where a failed drive costs more than the drive itself.

Deployments Where the Gold 22TB Is the Right Drive
- Server DAS (Direct Attached Storage): 12x Gold 22TB in a Dell R760 (SATA mode) or xFusion 5288 V7 = 264 TB raw in 2U/4U. For file servers, backup repositories, and archive volumes that do not need NVMe performance.
- S3-Compatible Object Storage: MinIO and Wasabi-style deployments where capacity per drive, not IOPS per drive, is the scaling metric. A 24-drive MinIO node with Gold 22TB delivers 528 TB raw — approximately 400 TB usable with erasure coding (EC 8+4).
- バックアップリポジトリ (Veeam/Commvault): 22TB drives double the capacity per bay compared to 12TB drives from 2020. A backup server with 12x Gold 22TB delivers 200 TB usable (レイド 6) - だいたい 4 years of backup retention for a 50-VM environment.
互換性のあるプラットフォーム
SATA 6Gb/秒, compatible with any server with 3.5-inch SATA bays. Dell PowerEdge R660/R760/R770, xFusion V7, Lenovo Thinksystem, MinIO nodes, TrueNAS, Proxmox. Works with PERC H730/H740/H750/H755/H965i in SATA mode.
