Built for high-capacity archive and hyperconverged storage environments, the WD Ultrastar HA340 12TB (Part No. 0B47061) combines conventional magnetic recording (CMR) reliability with enterprise-grade performance. At 12TB per drive, this 3.5-inch SATA solution delivers substantial capacity density while maintaining deterministic write behavior—critical for backup-to-disk infrastructure, video surveillance repositories, and distributed object storage clusters where per-terabyte cost efficiency matters.
The drive's 7200 RPM spindle paired with a 256 MB cache yields sequential read speeds up to 267 MB/s, supporting batch restore operations and sequential scan workloads typical in cold-tier and archive tiers. With 2 million TBW endurance rating, the HA340 12TB handles sustained RAID rebuild cycles and modest continuous I/O without accelerated wear. Air-filled CMR design eliminates SMR host-management overhead, ensuring straightforward compatibility with legacy SAS/SATA expanders and established storage controllers across on-premise and hybrid cloud deployments.
