WD 0F38581 - Ultrastar 14 TB internal Memory, 3.5 Zoll, SATA

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 capacities, plays a crucial role in reducing operating expenses.

Total Cost of Ownership (TCO) is a key factor in data center architecture. Higher-capacity hard drives are essential for 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 drives with lower capacity. Helium-filled hard drives with low power consumption and high reliability reduce energy and maintenance costs, contributing to lower operating expenses. For example, using 18 TB drives instead of 14 TB drives requires 22% fewer racks, and idle power consumption is 12% lower per TB. This results in 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.

• The first hard drive on the market with Energy-Assisted Magnetic Recording (EAMR) enhances write performance and thus data density.
• The first use of TSA technology (Triple State Actuator) enables precise head positioning.
