WD Ultrastar DC HC550 WUH721814AL5204 - Hard drive - 14 TB - internal - 3.5" - SAS 12Gb/s - 7200 rpm - buffer: 512 MB

Internal hard drives with higher capacities and lower TCO. Data center decisions are driven by TCO. The Ultrastar DC HC550, with 14TB, play a leading role in reducing TCO.

• CMR technology works with all capacity enterprise applications and environments
• HDD with Energy Assisted-Magnetic Recording technology
• Triple stage actuator
• HelioSeal design delivers outstanding power efficiency (Watts/TB)

• Total Cost of Ownership (TCO) drives the data center architecture
  Data center decisions are driven by TCO. Higher capacity hard drives play a leading role in reducing TCO. Higher capacity HDDs enable data centers to lower CapEx by reducing supporting hardware and system level costs when compared to lower capacity drives. Helium-sealed, low power, high reliability drives reduce energy and maintenance costs, contributing to OpEx savings. For example, a data center using 18TB HDDs vs. 14TB HDDs can require 22% fewer racks while consuming 21% less power per TB at idle, resulting in significant overall TCO reduction for data center environments.
• Raising the capacity bar
  Ultrastar DC HC550 integrates a suite of technologies on a 9-disk platform to create a high class of HDDs. 14TB capacity is achieved by combining technologies that improve areal density working together with technologies that improve performance and reduce power consumption.
