## Long description

Western Digital Ultrastar DC HC555 12TB is a 3.5" internal enterprise-class hard drive engineered for continuous data center and server operation. With 12 TB of capacity, 512 MB cache and 512e sector emulation, this SATA drive delivers sustained storage density and predictable performance for large-scale arrays, archival systems and mixed workload environments. It spins at 7200 RPM, communicates over SATA III (6 Gbps) and includes design characteristics for 24/7 use, such as high MTBF and defined shock and vibration tolerance.
Advantages
The Ultrastar DC HC555 combines high capacity with a large cache to improve throughput for sequential and random workloads. Its 7200 RPM rotational speed and 512 MB buffer help reduce latency while the SATA III interface supports up to 6 Gbps external transfer rates. Built for continuous operation, the drive features a high MTBF rating and low non-recoverable error rate, making it suitable for enterprise storage arrays. The drive’s mechanical and environmental tolerances—operating shock and vibration, wide temperature range and robust start/stop cycle rating—support reliable operation in server racks and dense storage enclosures.
Suitable for
High-capacity storage arrays and scale-out storage
Archival and cold storage where large capacity is required
Virtualization hosts and hyperconverged infrastructure
Database storage and sequential workload systems
Enterprise backup targets and nearline storage
