Western Digital Ultrastar DC HC550 18 TB Hard Drive - 3.5" Internal - SAS (12Gb/s SAS)

Internal hard drives with higher capacities and lower TCOData center decisions are driven by TCO. The Ultrastar DC HC550, with 14TB, 16TB & 18TB, play a leading role in reducing TCO.Total Cost of Ownership (TCO) Drives the Data Center ArchitectureData center decisions are driven by TCO. Higher capacity hard drives play a leading role in reducing TCO. An 18TB data center internal hard drive 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 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 with New TechnologiesUltrastar DC HC550
