Western Digital's Ultrastar HA340 4TB (Part Number 0B47076) is a proven workhorse for enterprise storage environments across the GCC region and beyond. Built on proven CMR (Conventional Magnetic Recording) technology, this 3.5-inch SATA drive delivers sustained sequential read speeds up to 267 MB/s with a 7,200 RPM spindle and 256 MB cache buffer, making it ideal for mid-tier NAS systems, RAID arrays, and distributed backup infrastructure where reliability and cost-per-terabyte matter equally.
The HA340 4TB excels in mixed-workload deployments: build resilient 4-bay NAS clusters for SMB file services, configure RAID-5 or RAID-6 arrays for departmental storage consolidation, or scale multi-drive surveillance systems for enterprise campuses. With 2 million terabytes written (TBW) endurance rating and enterprise-class MTBF specifications, this drive is engineered for 24/7 operation in climate-controlled data closets and server rooms. The 4TB sweet spot balances capacity density with operational simplicity—no exotic enclosures required, native SATA 6Gb/s compatibility with standard controllers, and proven longevity in production environments across Asia, Europe, and the Middle East.
