Western Digital Ultrastar DC HC510 10TB HDD

The Western Digital Ultrastar DC HC510 is a 10TB enterprise hard drive engineered for data centers, NAS systems, and large-scale storage arrays that demand around-the-clock reliability. Built on Western Digital's fifth-generation HelioSeal platform, the drive's hermetically sealed enclosure is filled with helium instead of air, reducing internal turbulence on the spinning platters. This design choice translates to lower power draw, reduced heat output, and the ability to pack more platters into the standard 3.5-inch form factor—advantages that add up significantly across dozens or hundreds of drives in a server rack.

With a workload rating of up to 550TB per year, the HC510 is built to handle the relentless read/write demands of enterprise applications, surveillance recording, and bulk data storage. Rotational Vibration Safeguard technology uses onboard sensors to counteract the vibrations caused by neighboring drives in dense enclosures, helping maintain consistent performance where it matters most. A 256MB cache and 7200 RPM spindle speed deliver solid sequential throughput for large file transfers, while the 2.5 million-hour MTBF rating and 5-year warranty provide the peace of mind that enterprise buyers expect from the Ultrastar line.
