WD Ultrastar DC HC560 3.5" 20000

The Western Digital Ultrastar DC HC560 is a high-capacity 3.5-inch hard drive designed for enterprise data center applications, offering 20 TB of storage capacity and helium-sealed technology for enhanced reliability and energy efficiency. This model features a SATA 6 Gb/s interface with a rotational speed of 7200 RPM and a 512 MB cache buffer for consistent performance under demanding storage workloads. The hard drive utilizes conventional magnetic recording technology (CMR) with 9 platters and 18 heads, providing sustained data transfer rates for cloud storage, big data analytics, and content delivery networks. With an annual workload rating of 550 TB and a mean time between failures (MTBF) of 2.5 million hours, this hard drive is designed for 24/7 operation in multi-drive environments. The helium-filled design reduces mechanical resistance and power consumption while maintaining stable operation in a temperature range of 5 °C to 60 °C. The hard drive measures 147 mm in width, 101.6 mm in length, and 26.1 mm in height, weighs approximately 670 grams, and features vibration protection technology for improved performance in multi-drive systems. The Ultrastar DC HC560 includes integrated data protection features such as error correction codes and thermal monitoring, making it suitable for use in servers, storage arrays, and enterprise backup systems, where data integrity and reliability are critical factors.
