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 HDD 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
