Western Digital 0B42266 Ultrastar DC HC330, 10TB, 3.5", SATA3 6GB/s, 7200 RPM, 256MB, 273 MB/S, CMR

Affordable capabilities and fast data access are important requirements for HDDs in the data centerIT managers must provide storage tiers as they implement custom-built solutions to meet their on-premises, off-premises, and cloud storage requirements. Helium-filled drives enable the highest capacities, while air-filled drives offer significant advantages. 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 adjust their budgets to meet their needs. The Ultrastar® DC HC300 Series helps meet data center requirements by offering capacities from 4TB to 10TB1, while increasing performance compared to previous generations. 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 7200 RPM with 6 Gb/s SATA or 12 Gb/s SAS interface in Advanced Format 4Kn and 512e format4. A 512n option is also available on 4 TB models to support legacy systems with native 512-byte block sizes.

Technology innovation drives efficiency and performance for traditional and legacy systemsThe Ultrastar DC HC300 series is based on a proven and cost-efficient air-based HDD platform design, featuring CMR (Conventional Magnetic Recording) technology in a 3.5-inch format. These HDDs use common hardware and firmware and offer a second-generation two-stage micro actuator to increase head positioning accuracy for better drive performance. Improving write performance is also supported by Western Digital's media caching architecture, a disk-based caching technology that provides a large cache area on the disk, increasing reliability and data integrity. Finally, the addition of a flash-based non-volatile cache (NVC) on both SATA and SAS models helps improve write performance.
