Product Description

When a server or storage array requires additional capacity without compromising reliability, the WD Ultrastar DC HC320 8TB is a compelling choice. Designed for continuous 24/7 operation, this enterprise-class hard drive supports an annual workload of up to 550TB.

The SAS 12Gb/s interface, 7200 RPM rotational speed, and 256MB cache provide fast, consistent data access, with media transfer rates of up to 255MB/s. Rebuild Assist helps shorten RAID array rebuild times, reducing the risks and downtime associated with drive replacement.

The micro actuator and rotational vibration compensation technology ensure precise head positioning, even in densely populated, high-demand drive enclosures. An MTBF rating of 2 million hours and an unrecoverable error rate of 1 per 10¹⁵ bits read further underline the drive's enterprise-class design.

The Secure Erase (SE) feature enables secure data erasure when the drive is decommissioned. The 512e sector format provides compatibility with a broad range of systems and applications.

The drive is suitable for servers, RAID arrays, block and file storage systems, virtualization environments, and enterprise archiving. The manufacturer's five-year warranty provides additional peace of mind for your IT infrastructure.

Ideal Applications

• Servers and RAID storage arrays

• Block and file storage systems

• Distributed and scalable storage environments
