Western Digital Ultrastar DC HC510 8TB 7200RPM SATA 6Gb/s 3.5-inch HDD

The Western Digital Ultrastar DC HC510 8TB is a purpose-built enterprise hard drive engineered for demanding data center environments requiring high sustained throughput, consistent low-latency access, and continuous 24/7 operation. Built on a conventional magnetic recording (CMR) architecture with helium-sealed hermetic design, the HC510 delivers full 8TB capacity within a standard 3.5-inch form factor while maintaining a lower operating power profile compared to air-filled drives of equivalent capacity. The hermetically sealed helium platform reduces internal turbulence, enabling tighter platter stacking, reduced weight, and improved thermal stability across extended operational periods.

Operating at 7,200 RPM with a SATA 6Gb/s interface, the Ultrastar DC HC510 (model HUH721008ALE600) is rated for up to 550TB per year workload capacity, making it suitable for write-intensive enterprise applications. The drive incorporates Western Digital's HelioSeal technology and supports a rotational vibration (RV) sensor to maintain performance integrity in multi-drive chassis and high-density enclosures. With a 256MB data buffer and mean time between failures (MTBF) of 2,500,000 hours, the drive is designed to meet the reliability expectations of enterprise storage deployments.

The HC510 is validated for compatibility with a broad range of enterprise storage platforms including NAS, SAN, JBOD, and direct-attached storage enclosures. Its CMR architecture ensures full compatibility with all standard RAID configurations including RAID 0, 1, 5, 6, and 10, making it a dependable choice for environments where data integrity, rebuild predictability, and long-term archival retention are operational priorities. Western Digital subjects this drive series to extensive enterprise-grade validation testing, aligning it with deployments across hyperscale, cloud, and on-premises infrastructure.

Ideal for

• High-capacity bulk storage tiers in enterprise NAS and SAN arrays requiring predictable CMR-based RAID rebuild behavior
• Active archive and cold storage repositories in data centers managing large-scale unstructured data growth
• Surveillance and video analytics infrastructure demanding continuous write throughput across multi-drive enclosures
• AI and machine learning data lake storage where large sequential dataset ingestion and retrieval are core operations
• Hyperscale and cloud object storage back-end nodes requiring high-density, low-power-per-terabyte drives
• On-premises enterprise backup and disaster recovery targets where sustained write workloads and drive longevity are critical
