Ultrastar DC HC550 - 18 TB
Model number: 0F38459

Highest storage capacity at low cost
When it comes to equipping data centres, decisions are based on costs. The Ultrastar DC HC550 with 14TB, 16 TB and 18 TB1 plays an important role in reducing operating costs.

Total cost of ownership (TCO) as a decisive factor for data centre architecture
Decisions when equipping data centres are based on costs. And hard drives with higher storage capacity play an important role when it comes to reducing costs. An 18 TB hard drive offers 29% more storage capacity in the same form factor compared to a 14 TB version. Higher capacity hard drives enable lower capital expenditure for data centres as less hardware is required and lower system costs are incurred than when using lower capacity drives. Helium-filled hard drives with low power consumption and high reliability reduce energy and maintenance costs, helping to reduce operating expenses. For example, by using 18TB drives instead of 14TB drives, 22% fewer racks are required and idle power consumption is reduced by 12% per TB. This leads to considerable savings in the total cost of ownership in the data centre.

More capacity with new technology
The Ultrastar DC HC550 establishes a new generation of hard drives with innovative technologies and nine magnetic discs. It offers 18 TB of storage capacity and combines technologies for higher data density with increased performance and reduced energy consumption.

-The first hard drive on the market with Energy-Assisted Magnetic Recording (EAMR) increases write performance and therefore data density.
-The first use of TSA technology (Triple State Actuator) enables precise head positioning. This improves performance and increases data density.
-The HelioSeal® technology is the foundation of Western Digital's high capacity hard drives and this is the sixth generation of HelioSeal products. Western Digital has sold more than 65 million HelioSeal products to date.
