WD HC550 Internal HDD Overview

The 16TB UltraStar DC HC550 7200 rpm SATA III 3.5" Internal HDD from WD is a high-performance, large-capacity drive designed for enterprise environments that have intensive data and storage needs. This drive has a storage capacity of 16TB and a 3.5" form factor with a SATA III 6 Gb/s interface, rotational speed of 7200 rpm, and 512MB cache that help to ensure uninterrupted data transfers at speeds of up 262 MB/s.

General Features
Total Cost of Ownership (TCO) Drives the Data Center Architecture
Data center decisions are driven by TCO. Higher capacity hard drives play a role in reducing TCO. 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. Higher capacity drives require fewer racks and consume less power per TB at idle, resulting in significant overall TCO reduction for data center environments.
Raising the Bar with Advanced Technologies
The Ultrastar DC HC550 integrates a suite of technologies on a 9-disk platform to create a new class of HDDs. It uses Energy-Assisted Magnetic Recording (EAMR) technology to improve writability and increase areal density, while a Triple Stage Actuator (TSA) enhances head-positioning accuracy, delivering better performance and increased areal density. Lastly, this drive uses HelioSeal technology, which is now in its 6th generation.
Trusted Reliability and Quality for Data at Scale
With its massive capacity and 2.5 million hour MTBF reliability rating, the UltraStar DC HC550 is made for object storage implementations. Object storage systems with erasure coding provide better data durability compared to RAID systems, given their tolerance for simultaneous error conditions. The DC HC550 offers security and encryption options to help protect data from unauthorized use, including SED models in both SATA and SAS. A SED-FIPS will be available in SAS configuration.
