Innovation to Support
Low-workload Applications

The HGST MegaScale DC™ 4000.B is designed to meet
the needs of the scale-out data center where low­power, high-capacity, cost-eective storage is essential.
MegaScale DC addresses low application workloads
that operate within 180TB per year. Typical low-workload
applications include multi-drive replicated environments,
disk-to-disk backup and restore snapshots, online
archives, big data stores and long-term data retention
that beneit from low-cost or energy usage.

Understanding Workload is Key

HGST oers a comprehensive product portfolio to
address the dierent workloads within the data center
so our customers can maximize their return. When
selecting hard disk drive, it’s important to consider the
application workload. Workload is deined as the amount
of work stress the HDD can endure during normal
operating conditions. To achieve high storage density,
components within the hard drive chassis move with
precision. This complex engineering requires that HDDs
have an optimized design rated for a speciic usage time
and workload range. Our products have the highest
reliability ratings for the rated workloads. To ensure
optimal eiciency, it’s critical that data center managers
make informed decisions when selecting the right
storage design with the right speciications for the right
application workload.

Minimizing Power Consumption

MegaScale DC drives leverage Advanced Power
Management technology which oers ive levels
of granularity to help manage power consumption
including: normal idle; unload idle; low RPM idle; standby;
and sleep. The standby and sleep modes consume less
than 1 watt, enabling archival applications to remain
online and ready to respond, yet at eco-friendly power
levels.

HGST Quality and Service

HGST’s MegaScale DC extends the company’s long­standing tradition of performance and capacity
leadership. The proven drive design enables high
reliability and availability to customer data. MegaScale
DC quality, performance and world class technical
support and service provides customers with a lower
total cost of ownership over previous generations.

HGST drives are backed by an array of technical
support and services, which may include customer and
integration assistance. HGST is dedicated to providing
a complete portfolio of HDD/SSD solutions to satisfy
today’s monumental computing needs.
