WD Ultrastar DC HC550 18 TB Hard Drive 3.5″ Internal 512MB SATA 7200rpm 512E SE NP3 DC HC550

.
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 requires 22% fewer racks while consuming 21% less power per TB at idle, resulting in signi?cant overall TCO reduction for data center environments.

Features

High Workload Rating

Delivering dependable performance to any storage environment, Ultrastar hard drives are designed with a workload rating up to 550TB per year, among the highest of any 3.5-inch hard drive.

Enterprise-class Storage to Rely On

Ultrastar is our top-end drive for data centers. With up to 2.5 million hours MTBF, Ultrastar hard drives deliver reliability and durability, are built for yearly operation (24x7x365) within the most demanding storage environments.

HelioSeal Technology

Featured in over 30 million Western Digital hard drives shipped, HelioSeal technology allows for higher capacities and lower power on large storage arrays. And now on its 5th generation design, HelioSeal technology is field-tested and proven to deliver high capacity, reliability, and power efficiency you can trust.

Vibration Protection

Enhanced Rotational Vibration Safeguard (RVS) technology uses sophisticated electronics to monitor the drive and correct linear and rotational vibrations in real time for improved performance versus traditional desktop drives in high-vibration environments.

Dynamic Fly-height Technology

Each read-write head’s fly height is adjusted in real time to ensure consistent performance for reduced errors and optimized reliability.

Dual-stage Actuator Technology

Ultrastar drives feature a dual-stage actuator head positioning system for a high degree of accuracy. The primary stage provides course displacement while the secondary stage uses piezoelectric motion to fine tune the head positioning to a higher degree of precision.

Compatibility Testing

All Ultrastar hard drives are extensively tested across a variety of popular OEM storage systems, SATA controllers, and host bus adapters to ensure ease of integration for a plug and play solution.

7200 RPM-Class

This family of 7200 RPM-class hard drives delivers the fastest performance with the highest workload rating of any drive in Western Digital’s hard drive lineup.
