Overview

Range/Series Overview


IMPORTANT: This Range/Series overview section describes the range of which this product belongs. Features of different versions might be mentioned and may not apply to the specific product on this page. Please view Specs for specification of product.

As the industry evolves to develop purpose-built solutions for growing data storage requirements, IT managers continue to rely on lower capacity drives that are economical to acquire, yet deliver quick and reliable data access for traditional data center applications. Ultrastar DC HC310 is a low-capacity HDD, that helps address economic and access requirements of many traditional IT workloads. Low capacity drives also help address architecture limitations. Part of the mid-capacity DC HC300 series, the Ultrastar DC HC310 is designed for traditional storage and server applications as well as distributed and scalable computing, including block and file storage architectures, providing fast 7,200 RPM performance and lower acquisition cost to help ease budget constraints. Ultrastar DC HC310 is offered with SAS interface.


Features Summary

  • Technology innovation delivers efficiency and performance for traditional and legacy systems
    Ultrastar DC HC310 is based on a 4-disk air platform design that uses conventional magnetic recording (CMR) technology in a 3.5-inch large form factor. Compared to the prior generation, Ultrastar 7K6000, the DC HC310 delivers a 12% performance boost and uses slightly larger-diameter media. It features a second-generation, dual-stage micro actuator 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, which also improves reliability and data integrity during unexpected power loss. Finally, the addition of flash-based non-volatile cache (NVC) on both SATA and SAS models helps improve write performance. The Ultrastar DC HC310 also includes a Rebuild Assist feature, which helps dramatically reduce RAID rebuild times and maintain system performance during the rebuild process.
  • Data security with trusted quality, reliability
    Compliance and privacy requirements drive the need for increased data security. Ultrastar DC HC310 helps protect data from unauthorized use by offering security and encryption options. SAS models offer hardware-based encryption options, including a Trusted Computing Group (TCG) Enterprise A, TCG with FIPS 140 - 2 certification, Level 2.
