Decisions regarding data center equipment are driven by costs. The Ultrastar DC HC550 is available in 14 TB, 16 TB, and 18 TB capacities. Total Cost of Ownership (TCO) is a crucial factor in data center architecture. Higher-capacity hard drives play an important role in cost reduction. An 18 TB hard drive offers 29% more storage capacity than a 14 TB version in the same form factor. Higher-capacity drives enable lower capital expenditures for data centers, as less hardware is needed and system costs are lower compared to using lower-capacity drives. Helium-filled hard drives with low power consumption and high reliability reduce energy and maintenance costs, contributing to a decrease in 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 operating costs 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.
