WD Ultrastar DC HC550 18 TB Festplatte (8,9 cm (3,5 Zoll), intern, SATA

Decisions regarding the equipment of data centers are driven by costs. The Ultrastar DC HC550, available in 14 TB, 16 TB, and 18 TB capacities, considers total cost of ownership (TCO) as a crucial factor in data center architecture. Hard drives with higher storage capacities play an important role in cost reduction. An 18 TB hard drive offers 29% more storage capacity compared to a 14 TB version within the same form factor. Higher-capacity hard drives enable lower capital expenditures for data centers, as less hardware is required and system costs are lower than when using drives with lower capacities. Helium-filled hard drives with low power consumption and high reliability reduce energy and maintenance costs, thereby contributing to lower operating expenses. For example, using 18 TB drives instead of 14 TB drives results in a 22% reduction in the number of racks needed, and idle power consumption is 12% lower per TB. This leads to significant savings in total cost of ownership for the data center. More capacity with new technology: The Ultrastar DC HC550 establishes a new generation of hard drives with innovative technologies and nine magnetic disks. It offers 18 TB of storage capacity and combines technologies for higher data density with improved performance and reduced energy consumption.
