Western Digital 8TB DC HC320 HDD. Bring medium capacity drives to your data centre
The Ultrastar DC HC300 series offers low to medium capacity drives that are economical to purchase, yet provide fast and reliable data access for traditional data centre applications.

Economy and access speed: Key requirements for low-capacity SATA HDDs in the data centre
As the industry evolves to develop fit-for-purpose solutions for growing data storage needs, IT managers continue to rely on low-capacity drives that are economical to purchase, yet provide fast and reliable data access for traditional data centre applications. The Ultrastar® DC HC320 is an 8TB1 drive designed for workloads of up to 550TB per year and meets the economic and access requirements of many traditional IT workloads. Low capacity drives also help with architectural constraints. The Ultrastar DC HC320 is part of our mid-capacity DC HC300 series and is designed for traditional storage and server applications as well as distributed and scalable computing, including block and file storage architectures. It offers fast 7,200 RPM performance and lower acquisition costs to reduce budget constraints. Ultrastar DC HC320 is offered with either 6Gb/s SATA or 12Gb/s SAS interface in 512e9 format.

Technology innovation delivers efficiency and performance for traditional IT systems
Ultrastar DC HC320 is based on a proven 5-disk air platform design that utilises conventional magnetic recording (CMR) technology in a 3.5-inch form factor. Compared to the previous generation Ultrastar 7K6000, the DC HC320 offers 33% more capacity, a performance increase of up to 12% and uses media with a slightly larger diameter. It features a second-generation two-stage microdrive that improves head positioning accuracy for better drive performance. The increase in write performance is also supported by Western Digital’s Media Cache architecture, a hard drive-based cache technology that provides a large cache area on the drive, improving reliability and data integrity in the event of unexpected power failures. Finally, the addition of a flash-based non-volatile cache (NVC) on both SATA and SAS models helps improve write performance. The Ultrastar DC HC320 also features a Rebuild Assist function that can dramatically reduce RAID rebuild times and maintain system performance during the rebuild process. Further information can be found in our technical document Rebuild Assist.
