P0F38581 0F38581 Western Digital WD Ultrastar DC HC550 14TB 3.5' SATA 512MB 7200RPM EAMR SE 5yrs Warranty-WUH721814ALE6L4 OVERVIEW Internal hard drives with higher capacities and lower TCO otal 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, Full Specifications Features - CMR technology works with all capacity enterprise applications and environments - Industry's first HDD with Energy Assisted-Magnetic Recording technology - Industry's first Triple Stage Actuator - HelioSeal design delivers outstanding power efficiency (Watts/TB) Capacity 14TB Form Factor 3.5-Inch Connector SATA Compatibility Windows, Windows Server, Linux Interface SATA/ SAS Transfer Rate up to 262MB/s Disk Speed (RPM) 7200 RPM Recording Technology EAMR Cache Size 512MB Security SE Warranty 5-Year Limited Warranty Dimensions (L x W x H) 147mm x 101.6mm x 26.1mm Weight 690gms Operating Temperature 5°C to 60°C Non-Operating Temperature -40°C to 70°C Drive 3.5' Certifications BSMI, ICES-003/NMB-003, CE, FCC, KC, Maghreb, RCM, UKCA, VCCI, CB-Scheme, TUV, UL
