0F27503 WD Ultrastar DC HC510 10TB SATA 256 MB 3.5" Server HDD

High-Density 3.5in Datacenter SATA HDD featuring 4Kn CMR and SED security with the 0F27503

The 0F27503 is a WD Ultrastar DC HC510 10TB internal datacenter HDD designed for always-on bulk storage tiers where predictable latency, sustained throughput, and fleet manageability matter. As a 3.5in 7200 RPM platform on SATA, the 0F27503 integrates cleanly into standard rack server backplanes and storage enclosures, supporting enterprise RAID layouts and high-bay capacity expansion without changing the host architecture.

Architecturally, the 0F27503 pairs CMR recording with 4Kn native sectors to align with modern filesystems and array controllers optimized for 4KB I/O, reducing write amplification compared to legacy 512e designs in many workloads. A 256MB cache helps absorb bursty traffic, while the helium-filled mechanical design targets lower friction and tighter power behavior for dense deployments. For security-sensitive environments, the 0F27503 implements hardware-based AES-128 Self-Encrypting Drive capabilities to enforce at-rest encryption with minimal CPU overhead, and it supports the Power Disable feature to streamline remote power cycling in large-scale chassis.

Why Choose the 0F27503?

The 0F27503 delivers a balanced density-to-performance profile for capacity pools, backup repositories, and archival tiers that must run 24/7 with consistent service levels. With enterprise-class reliability characteristics and an architecture that scales efficiently across multi-drive RAID groups, the 0F27503 supports predictable expansion planning and standardized sparing strategies across racks and sites.

WD engineers Ultrastar platforms for datacenter operational stability, emphasizing controlled acoustics and vibration behavior, tight thermal envelopes, and qualification discipline that aligns with modern storage servers, JBODs, and hyperscale-inspired serviceability expectations.

Key Applications:

• RAID capacity tiers in rack servers
• Backup and recovery repositories
• Nearline archival storage
• Scale-out object storage nodes
• Security-focused data retention
