Description
Additional information

Total Cost of Ownership (TCO) Drives the Data Center Architecture

Datacenter decisions are driven by TCO. Higher-capacity hard drives play a leading role in reducing TCO. An 14TB 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.
