WD Ultrastar HA340 6TB (Part No. 0B46950) is a purpose-built enterprise storage drive engineered for high-capacity RAID arrays, NAS systems, and continuous-duty data centers across the GCC and Asia-Pacific regions. With 6TB capacity, 7,200 RPM performance, and SATA 6Gb/s connectivity, this drive delivers the optimal balance between density and cost-per-terabyte for organisations scaling fixed-bay storage infrastructure without transitioning to helium-filled platforms.
The HA340 6TB excels in surveillance retention systems, regional media archives, backup appliances, and dense RAID-6 configurations where mixed read/write patterns demand reliable sustained throughput. Its 256 MB cache and 267 MB/s sequential read speed support workloads rated up to 550 TB annually, while the 2 million TBW endurance rating ensures multi-year reliability in continuous duty cycles. CMR technology provides consistent random-access performance across temperature-controlled data centre environments, making it ideal for tier-2 cold storage, archival tiers, and enterprise NAS deployments where cost efficiency outweighs extreme-density requirements.
