WD Ultrastar DC HC550 14TB SE

Highest storage capacity at low cost

Decisions regarding data center equipment are driven by costs. The Ultrastar DC HC550, available in 14 TB, 16 TB, and 18 TB, plays a crucial role in reducing operating expenses.

Total cost of ownership (TCO) as a key factor in data center architecture

Decisions regarding data center equipment are cost-driven. High-capacity hard drives play an important role in cost reduction. An 18 TB hard drive offers 29% more storage capacity compared to a 14 TB model in the same form factor. Higher-capacity hard drives enable lower capital expenditures for data centers, as less hardware is needed and system costs are lower than when using lower-capacity drives. Helium-filled hard drives with low power consumption and high reliability reduce energy and maintenance costs, thus contributing to lower operating expenses. For example, using 18 TB drives instead of 14 TB drives results in 22% fewer racks needed, and idle power consumption is 12% lower per TB. This leads to significant savings in total operating costs in 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.
