WD Ultrastar DC HA340 4TB 256MB SATA SE 512e WUS721204BLE6L4

Overview

Economical Capacities and Fast Data Access Key Requirements for HDDs in the Data Center

IT managers need to offer storage tiers as they deploy purpose-built solutions to meet their on-prem, off-prem & cloud storage requirements. While helium-filled drives enable the highest capacities, air-filled drives offer important benefits. With a lower TCA (total cost of acquisition), legacy options, and higher access density (IOPs/TB), they are the perfect choice for maintaining a desired level of performance while allowing customers to tailor budgets to meet their needs.

The Ultrastar DC HA340 helps to address data center requirements by providing capacities from 4TB to 8TB while implementing the latest in HDD recording technologies. They are designed for a variety of applications including traditional storage arrays, rack-mounted storage enclosures and server-based distributed storage systems, as well as distributed and scalable computing, including block and file storage architectures. They are offered at 7,200 RPM with 6Gb/s SATA interface in Advanced Format 512e format.

Technology Innovation Delivers Efficiency and Performance for Traditional and Legacy Systems

Ultrastar DC HA340 drives are based on a proven and cost-efficient air-based HDD platform design, with Conventional Magnetic Recording (CMR) technology in a 3.5-inch large form factor. These HDDs leverage common hardware and firmware while featuring a second-generation, dual-stage microactuator to enhance head positioning accuracy for better drive performance. Write performance gains are also supported by Western Digital’s media cache architecture, a disk-based caching technology that provides a large cache area on the disk, improving reliability and data integrity. Finally, the addition of a flash-based nonvolatile cache (NVC) helps improve write performance.

Trusted Reliability and Quality

Ultrastar DC HA340 drives extend Western Digital’s long-standing tradition of reliability leadership with a 2M-hour MTBF rating (projected), workloads up to 550TB per year, and a 5-year limited warranty.
