Western Digital Ultrastar DC HC550 14 TB 3.5″ Internal Hard Drive, 512MB, SATA 7200rpm, SATA 6Gb/s, Compatible With Windows / Server and Linux | 0F38462 / WUH721414AL604

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 14TB 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.
Highlights
14 TB storage capacity in 3.5-inch format
Conventional Magnetic Recording (CMR) technology for reliable data storage in enterprise environments
Reliable construction, proven in the fifth generation
HelioSeal ensures high power efficiency (Watt/TB)
MTBF of 2.5 million hours
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 internal hard drive 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 internal hard drives in the industry to harness Energy-Assisted Magnetic Recording (EAMR) technology improves writability and therefore increases areal density.
● The industry’s first Triple Stage Actuator (TSA) enhances head-positioning accuracy, delivering better performance and increased areal density.
● HelioSeal® technology is the foundation for Western Digital’s high capacity HDDs and this is the 6th generation of HelioSeal product. Western Digital has shipped >65 million HelioSeal products to date.
