Western Digital Ultrastar DC HC510 10TB 7200RPM SAS 12Gb/s 3.5-inch Helium Enterprise HDD

The Western Digital Ultrastar DC HC510 10TB (HUH721010AL5204) is a 3.5-inch helium-sealed enterprise hard drive engineered for demanding data center environments. Built on HelioSeal technology, the drive's hermetically sealed enclosure is filled with helium gas rather than air, reducing internal turbulence and enabling higher platter density while lowering power consumption and operating temperature compared to conventional air-filled designs. The SAS 12Gb/s interface delivers dual-port connectivity with full 12Gb/s transfer bandwidth, supporting enterprise storage arrays, RAID controllers, and high-availability configurations that require path redundancy and robust command queuing.

The HC510 spins at 7,200 RPM and is rated for up to 550TB per year workload, making it suitable for always-on mixed read/write environments where sustained throughput and reliability are paramount. The drive incorporates Western Digital's vibration compensation technology to maintain consistent performance when deployed in high-density multi-drive enclosures where rotational vibration from neighboring drives would otherwise degrade tracking accuracy. A 256MB cache buffer supports efficient data staging for sequential and random I/O patterns typical of large-scale storage workloads.

Designed to carry a 2.5 million hour mean time between failures (MTBF) rating, the Ultrastar DC HC510 targets hyperscale cloud, enterprise NAS, object storage, and tiered storage deployments across verticals including media and entertainment, financial services, and high-performance computing. Its compatibility with SAS-3 backplanes and backward compatibility with SAS-2 infrastructure makes it a practical choice for both greenfield data center builds and capacity expansion within existing SAS ecosystems serving UAE, GCC, EMEA, and APAC enterprise buyers.

Ideal for

• Hyperscale and colocation data center bulk storage tiers requiring high-capacity, high-durability SAS drives in dense JBOD or RAID enclosures
• Enterprise NAS and SAN platforms where dual-port SAS redundancy and sustained 550TB/year workload ratings are mandatory for business continuity
• AI and machine learning data lake storage, providing high-capacity sequential read throughput for large training dataset ingestion pipelines
• Media and entertainment asset repositories storing uncompressed video, RAW image archives, and post-production project files demanding both capacity and consistent transfer rates
• Cloud object storage clusters such as OpenStack Swift or Ceph-based deployments where helium-sealed drives reduce per-drive power draw across thousands of nodes
• Financial services and compliance archiving environments requiring long-term, high-reliability storage with enterprise-grade error recovery and vibration compensation in multi-drive chassis
