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. An 18TB data center HDD provides 29% more capacity in the same form factor as a 14TB HDD. 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 requires 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 with New Technologies
Ultrastar DC HC550 integrates a suite of technologies on a 9-disk platform to create a new class of HDDs. 18TB capacity is achieved by combining technologies that improve areal density working together with technologies that improve performance and reduce power consumption.
Trusted Reliability and Quality for Data at Scale
With its massive capacity and 2.5M MTBF (projected) reliability rating, the Ultrastar DC HC550 is ideal for object storage implementations. Object storage systems with erasure coding provide better data durability compared to RAID systems, given their tolerance for simultaneous error conditions.
  • CMR technology works with all capacity enterprise applications & environments
  • Reliable, field-proven, 6th generation design
  • Industry’s first HDD with Energy-Assisted Magnetic Recording technology
  • HelioSeal® design delivers outstanding power efficiency
  • 2.5M hours (projected) MTBF2 rating
