Western Digital 0F27454 10TB Ultrastar DC HC510 HDD

The Western Digital Ultrastar DC HC510 (0F27454) is a 10TB enterprise-class hard drive built for environments where high capacity, reliability, and sustained performance are non-negotiable. At the heart of this drive is Western Digital's proprietary HelioSeal technology, which hermetically seals helium gas inside the drive enclosure. Because helium is significantly less dense than air, internal drag and turbulence are reduced, allowing more platters to be packed into the same 3.5-inch form factor while simultaneously lowering power draw and operating temperatures. The result is a drive that delivers 10TB of storage with enterprise-grade endurance.

The HC510 operates at a 7200 RPM spindle speed with a generous 256MB cache buffer and connects via the widely supported SATA 6 Gb/s interface, making it compatible with a broad range of enterprise servers, NAS units, and storage arrays. One important consideration is the power-disable feature built into the SATA power connector. While modern systems generally support this function, legacy hardware may not properly initialize the drive without the included Molex-to-SATA adapter cable. Western Digital designed this drive for capacity-dense server environments, cloud and hyperscale storage, big data analytics platforms, and surveillance systems where continuous operation and data integrity are essential.
