Western Digital Ultrastar DC HC550 18TB Data Center HDD

Description The 18TB/16TB Ultrastar DC HC550 HDDs are the first commercial implementation of Energy-Assisted Magnetic Recording technology and utilize the industry’s first Triple Stage Actuator. These technologies, integrated with HelioSeal on a 9-disk platform, deliver the highest areal density and unmatched Total Cost of Ownership for customer and market needs. Total Cost of Ownership (TCO) Drives the DataCenter Architecture Datacenter 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. 14TBHDDs requires 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 IOPS and reduce power consumption             Specifications SKU 0F38459 Specifications Interface SATA 6 Gb/s Capacity 18 TB Error rate (non-recoverable bits read) 1 in 10^15 MTBF (M hours) 2.54 Annualized Failure Rate (AFR) 0.35% Operating (W, typical) 6.55 Idle (W) 5.66 Brand WESTERN DIGITAL Weight 0.690000   Keywords ContentQuestion answer Content
