## Long description

The Western Digital Ultrastar DC HC320 is an internal 3.5" SAS hard disk drive with 8 TB capacity, 7200 RPM rotational speed and a 256 MB cache. Engineered for traditional data center and enterprise server environments, this drive is designed to deliver high storage density and consistent performance for mixed workload applications. With a rated workload capability up to 550 TB per year and a mean time between failures (MTBF) of 2,000,000 hours, the Ultrastar DC HC320 targets installations where reliable, cost-effective bulk storage and predictable access are required.
Advantages
The Ultrastar DC HC320 combines a high-capacity 8 TB design with 7200 RPM performance to provide faster access times than lower-speed archive drives while keeping acquisition cost lower than higher-capacity models. A 256 MB buffer helps smooth sustained transfers and random access patterns common in file and block storage. The drive’s SAS interface supports enterprise connectivity and integration into server and storage arrays used in data centers. The specified workload rate and MTBF offer a clear indicator of suitability for continuous operation in enterprise environments.
Suitable for
 Enterprise file servers and block storage arrays
 Data center bulk storage and archival systems with active access
 Distributed and scale-out computing nodes requiring high-density HDDs
 Virtual machine storage where balanced capacity and performance are needed
When it may not be suitable
This drive is not optimized for workloads that demand the highest IOPS or the lowest latency possible, such as latency-sensitive high-frequency trading systems or extremely random, write-heavy databases that benefit more from NVMe SSDs. It may also be less appropriate where very low power consumption or the smallest physical footprint is the primary concern.
Key specifications
 Capacity: 8,000 GB
 Form factor: 3.5"
 Interface: SAS (Serial Attached SCSI)
 Rotational speed: 7200 RPM
 Cache: 256 MB
 Rated workload: up to 550 TB per year
 Mean time between failures (MTBF): 2,000,000 hours
 Weight: 0.715 kg
How to use
Install the Ultrastar DC HC320 into a compatible 3.5" drive bay that supports SAS connectivity. Ensure the server or storage enclosure firmware and HBA/RAID controller support the drive’s capacity and SAS link rate. Configure the drive within your storage array or host operating system according to your storage architecture—single-disk, RAID group, or software-defined storage cluster—observing manufacturer guidance for RAID rebuilds and drive rebalancing. Regularly monitor drive health and SMART attributes through your storage management tools to detect early signs of degradation.
What to consider before purchase
 Confirm chassis and controller compatibility with 3.5" SAS HDDs and 8 TB drive support.
 Evaluate whether a 7200 RPM enterprise HDD matches your IOPS and latency requirements versus SSD alternatives.
 Plan RAID level and redundancy to match the rated workload and expected uptime.
 Consider cooling, power budget, and physical drive density in your rack or enclosure.
Usage recommendations
Use this drive in scenarios where balanced capacity, enterprise-class reliability, and cost-effective performance are required—examples include primary bulk storage for active archives, virtual machine repositories, and scale-out file or block storage systems. Maintain appropriate redundancy and monitoring to maximize operational availability.
