0F27455 WD Ultrastar DC HC510 8TB SATA 256 MB 3.5" Server HDD

High-Density 3.5in Datacenter SATA HDD designed for 24x7 storage tiers with the 0F27455

The 0F27455 is an 8TB WD Ultrastar DC HC510 3.5in internal datacenter HDD engineered to deliver consistent capacity economics for servers and JBOD enclosures using a SATA interface. As a 7200RPM CMR drive, the 0F27455 is optimised for predictable write behaviour and sustained sequential throughput, making it a practical building block for high-density storage pools that must remain stable under continuous duty cycles.

In modern platforms where PCIe lanes are reserved for NVMe tiers and accelerator expansion, the 0F27455 supports scalable capacity growth through standard SAS/SATA backplanes and HBA connectivity without consuming premium PCIe resources. A 256MB cache and 4Kn (512e emulation) sector format help align the 0F27455 with contemporary OS and RAID implementations, while helium-filled mechanics contribute to controlled power and thermal characteristics for dense racks.

Why Choose the 0F27455?

The 0F27455 is suited to architects balancing density-to-performance for bulk storage, where reliability and operational consistency are prioritised over low-latency media. With 2.5M hours MTBF, the 0F27455 supports enterprise refresh cycles and large drive counts, enabling predictable scaling in capacity tiers, backup repositories, and general-purpose datacenter pools.

WD designs Ultrastar drives around datacenter reliability, serviceability, and standards-based integration, aligning mechanical engineering, firmware behaviour, and qualification processes to support multi-vendor server and storage ecosystems at scale.

Key Applications:

• Capacity tiers in rack servers and JBODs
• Backup and archive repositories
• General-purpose datacenter storage pools
• Sequential ingest and retention workloads
