Total Cost of Ownership (TCO) Drives the Data Center Architecture
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 insignificant overall TCO reduction for data center environments.
