WD Ultrastar DC HA340 8TB SATA Internal HDD - 3.5" CMR Enterprise Drive for Data Centers

The WD Ultrastar DC HA340 8TB hard drive is the data center-grade solution built to deliver scalable capacity, dependable performance, and robust reliability for traditional storage arrays, rack-mount environments, and legacy systems. Leveraging Conventional Magnetic Recording (CMR) technology on a 3.5-inch form factor with a SATA/600 interface, this drive is engineered to support continuous operation in demanding data-center workloads while maintaining compatibility with existing SATA backplanes and controllers. Ideal for high-capacity deployments, the DC HA340 combines dense storage with enterprise-grade characteristics to help organizations manage growing datasets efficiently.

• 8 TB enterprise-class storage with Conventional Magnetic Recording (CMR) delivers large, predictable capacity and steady throughput for mixed workloads. This enables efficient consolidation, archival, and hot data access in traditional storage arrays and older infrastructure that requires familiar SATA interfaces.
• Designed for 24x7 operation in data centers, the DC HA340 prioritizes reliability and data integrity under continuous use. Built to withstand ongoing workloads typical of rack-mount deployments, it supports sustained performance in demanding environments where uptime matters.
• SATA 6Gb/s interface (SATA/600) ensures broad compatibility with a wide range of servers, controllers, and backplanes. This simplifies deployment in existing infrastructures while delivering solid data-transfer rates for day-to-day read and write tasks.
• 3.5-inch form factor enables straightforward integration into standard server chassis, drive bays, and storage enclosures. The drive is designed to be easily swapped into traditional arrays and legacy systems without requiring specialized adapters or backplanes.
• Energy-conscious design and thermal efficiency help manage power consumption and heat in dense data-center racks. Lower power while delivering dependable performance can contribute to a lower total cost of ownership (TCO) in environments with large-scale storage requirements.
