Western Digital Ultrastar DC HC550 - 18TB
Overview
Highest Capacities for Lower TCO
Data center decisions are driven by TCO. The
Ultrastar DC HC550, with 16TB & 18TB1, play a leading role in reducing
TCO.
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.
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.
- The first HDD in the industry to harness Energy-Assisted Magnetic
Recording (EAMR) technology improves writability and therefore increases areal
density.
- The industrys first Triple Stage Actuator (TSA) enhances head-positioning
accuracy, delivering better performance and increased areal
density.
- HelioSeal technology is the foundation for Western Digitals high capacity
HDDs and this is the 6th generation of HelioSeal product. Western Digital has
shipped >65 million HelioSeal products to date.
