16TB Ultrastar DC HC550 WUH721816ALE6L4, 7200 RPM, SATA 6Gb/s, 512e/4Kn, 512MB cache, SIE, 3.5" HDD
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 can require 22% fewer racks while consuming 21% less power per TB at idle, resulting in significant overall TCO reduction for data center environments ** SINGLE P
