Ultrastar DC HC300 Series

Delivering Economics and Access Speed to Data Center Applications and Workloads

As the industry evolves to develop purpose-built solutions for growing data storage requirements, IT managers continue to rely on mid-range capacity drives that are economical to acquire, yet deliver quick and reliable data access for traditional data center applications. Designed to handle workloads up to 550TB per year, the Ultrastar DC HC300 series is a proven air-platform design that delivers up to the industry leading 10TB of capacity to help address the economic and access-density requirements of many data center workloads. Ideal for storage and server applications, as well as distributed and scalable computing (including block and file storage architectures), the Ultrastar DC HC300 series provides fast 7,200 RPM spindle speeds and is offered in either 6Gb/s SATA interface with advanced format 512e3 sector size.

Solves Access Density Challenges

Economical Capacity

4TB, 6TB, 8TB, and 10TB models for lower acquisition cost

High Performance

Fast data access with 7200 RPM speed, transferring up to 255 MB/s

Expanding our Ultrastar HC300 Family to 10TB
The Ultrastar DC HC330 is based on a proven and cost-efficient air-based HDD platform design utilizing six disks and conventional magnetic recording (CMR) technology in a 3.5-inch large form factor. Compared to our prior 10TB product, the DC HC330 delivers the same capacity while using fewer disks. It leverages common hardware and firmware from the existing DC HC300 family of 4TB, 6TB and 8TB capacities and features a second-generation, dual-stage micro actuator to enhance head positioning accuracy for better drive performance. Write performance gains over the prior 10TB are enabled by an improved media cache architecture, that incorporates a flash backed DRAM cache in addition to the existing disk based caching technology that provides a large cache area on the disk media.

Data Security with Trusted Quality, Reliability
New government regulations on data privacy and security requirements drive the need for increased security features on storage devices. The Ultrastar DC HC330 helps protect data from unauthorized use by offering security and encryption options. SATA models offer hardware-based encryption options, which includes both Sanitize Crypto Scramble / Erase functionality and TCG encryption (Trusted Computing Group, Enterprise SSC). The Ultrastar DC HC330 extends Western Digital’s long-standing tradition of reliability leadership with a 2M-hour MTBF4 rating, workloads up to 550TB per year, and a 5 year limited warranty
